NASCAR exhibit arrives in San Diego!

If you’re a NASCAR fan, you probably know that very special races are coming in 2026 to Naval Air Station North Island in Coronado. But did you know an equally special NASCAR exhibit recently opened at the San Diego Automotive Museum in Balboa Park?

The exhibition is titled NASCAR: Design and Innovation. A bunch of incredible vehicles are on display in the museum, just in time for the coming races across San Diego Bay!

I visited the Automotive Museum today and was blown away. Not only can you peer into a variety of different race cars, but you can learn about the evolution of NASCAR racing, including advances in vehicle design and technology.

A large part of the exhibition celebrates old Cajon Speedway, and remembers those who raced stock cars in San Diego’s East County years ago, from the oval track’s opening in 1961 until it closed in 2004.

I personally started paying attention to NASCAR a while back because seven-time NASCAR Cup Series champion Jimmy Johnson grew up in El Cajon. Perusing the exhibit, I noticed a reference or two to his legendary career.

The coming street races at NAS North Island will celebrate the United States Navy’s 250th anniversary. The event, running from June 19 to 21, 2026, will feature a 3.4-mile, 16-turn circuit with unique features like “Carrier Corner,” where racing occurs between two docked aircraft carriers! The big weekend will include races for the Truck Series, Xfinity Series, and the NASCAR Cup Series.

Should be exciting!

A few photos from my museum visit today…

San Diego submersible in Star Trek: Enterprise!

The Maritime Museum of San Diego recently acquired DeepFlight I, a unique “flying” underwater submersible developed in the late 1990s. You can read more about this amazing, advanced submersible here.

Visitors to the San Diego museum might be astonished to learn that this one-of-a-kind prototype appears in every episode of Star Trek: Enterprise!

DeepFlight I can be seen momentarily in the Star Trek: Enterprise introductory sequence, which begins every episode. The sequence depicts the evolution of human technology and exploration. DeepFlight I appears at the 34 second mark here!

Super cool!

Explore emerging ocean technology in San Diego!

A special event is coming up next Saturday, November 15, 2025. Visitors to the Maritime Museum of San Diego will have the opportunity to explore how emerging technologies are transforming how we use and protect ocean resources.

The event is free with General Admission and is perfect for families, students and anyone interesting in learning about blue technology. Hours are 10 am to 4 pm.

What is Blue Tech? It’s a category of advanced technologies focused on the sustainable development of the world’s oceans and coasts, also known as the Blue Economy.

According to one sign in the Maritime Museum, there will be hands-on exploration and interactive experiences concerning underwater robots, engineering, data tools and more. Student marine clubs will be there with their own innovations, too!

Super cool!

Some high tech equipment I spotted today near the sign…

AI experiment: Martians arrive in San Diego!

I had a fun idea for a new AI experiment!

Last night I was rereading H. G. Wells’ The War of the Worlds, when suddenly I wondered… What crazy images would the AI Drawing Assist function of my Samsung Galaxy smartphone create, should I use the text prompt: “Martians arrive in San Diego” and tap Generate.

I had my phone create the images in Pop Art style. That explains why words are sometimes splashed as if in a comic book. In many instances, the AI misspelled San Diego or produced absurd words.

I selected the best, most diverse images out of many that were produced.

Most had boats in a bay and flying saucers descending above a city that resembles San Diego. Certain skyscrapers like those of the Manchester Grand Hyatt are recognizable, even if oddly drawn or positioned.

A few surprising images had the green Martians themselves!

This is the third time I’ve experimented with the AI Drawing Assist on my phone. Would you like to see some more bizarre results?

Strange images of “Balboa Park at sunset” are here.

Eye-popping images of “San Diego 100 years in the future” are here!

Help save a young boy’s life!

The kiddo in the above photo is named Paxton. He desperately needs your help!

I learned from his dad that Paxton has a very rare genetic mutation. He has a devastating neurodegenerative mutation on the CLCN6 gene. Paxton will be part of a clinical trial for a promising new lifesaving treatment, but funds need to be raised.

Scientists at UMass Worcester, Chan School of Medicine, Horae Gene Therapy Center, are developing a first of its kind gene therapy for CLCN6 mutations. Paxton will be the patient in the clinical trial.

To read Paxton’s story, click here.

You can help!

I learned from Paxton’s father during the Adams Avenue Street Fair that funds can be raised via GoFundMe and WeWard. Also, you can donate via VENMO (@Cure_CLCN6_Inc) or ZELLE (Cure CLCN6, Inc.).

Here’s the GoFundMe page.

You can easily raise funds simply by walking and using the WeWard App. Create your profile (using referral code ZealousBumblebee1136), then from the Social Tab click Communities then +Join. Enter Code CURE2360 to join the Cure CLCN6 Community.

Deep Flight submersible arrives at Maritime Museum!

Check out what arrived at the Maritime Museum of San Diego yesterday! This super cool “Deep Flight” submersible!

This electric, one-man submersible was developed about 15 years ago by Hawkes Ocean Technologies. It’s now on display in the museum’s steam ferry Berkeley, in a spot where many model ships can be viewed.

I’m reasonably sure this is DeepFlight I, a submersible that served as a technology testbed for DeepFlight II. You can see a photo and learn more about Hawkes Ocean Technologies on this website.

The exhibit is so brand new, the submersible is still on rollers and there’s no information sign in the museum yet. (I was told that to roll the submersible into the Berkeley, part of the museum’s front desk had to be removed!)

While I don’t know too much right now, I’ll endeavor to learn more tomorrow when the Maritime Museum of San Diego has a special member event. I’ll provide more info here in an update.

But look at how cool this thing is! Imagine lying prone, squeezed inside the narrow craft, down in the mysterious depths of the sea, flying along silently like an underwater aircraft, water and sea life all around!

UPDATE!

A few days later, I noticed two of the historic submersible’s wings had been reinstalled.

A sign also points visitors to a cool YouTube video concerning the DeepFlight I. Watch it here.

UPDATE!

A sign appeared later. I was surprised to learn DeepFlight I briefly appears in the introductory film sequence of Star Trek: Enterprise!

See it 34 seconds into the YouTube video here!

March of Transportation mural in Balboa Park.

Visitors inside the world-famous San Diego Air & Space Museum in Balboa Park should look up. Not only will they see amazing aircraft exhibits suspended from the ceiling, but they might notice a very long mural painted along the museum’s circular inner wall.

The March of Transportation mural was created in 1936 for the California Pacific International Exposition. At over 9,300 square feet, it’s the largest mural of its kind found in North and South America.

Because so many cool aviation displays are jammed into the museum, I found it difficult to photograph large segments of the mural. But I’ve captured several glimpses, so you can get the idea of how the art appears.

A couple years ago I photographed the very end of the mural, which depicts futuristic forms of transportation (as conceived almost a hundred years ago). You can see those photos here.

Several murals decorated the Ford Building during the California Pacific Exposition in 1935. After the Exposition, the Ford Motor Company deeded the building to the City of San Diego for use as the “Great Hall of Transportation.” In preparation for the 1936 Exposition, this large mural was commissioned to express the theme–“The March of Transportation.”

The 1936 “Great Hall of Transportation” exhibits included vehicles of all ages, from reed boats, to the locomotive, to the concepts of air and space travel. The mural, 18 feet high, continues along the inner circular wall for 468 feet…

Master Artist Juan Larrinaga served as the Art Director for the 1935 and 1936 Expositions. He was assisted by New York illustrator, Charles B. Falls, and artists P.T. Blackburn, Mahlan Blane and Nicolas Reveles. Larrinaga labored long hours to produced the drawings from the artist assistants to fill in. More than 40 persons eventually contributed their talent and energy to the completion of the mural.

After years of deterioration, the building began a restoration in 1977. In 1979 the mural, too, was restored.

While this artwork depicts world history, it is also an important part of San Diego’s uniquely rich history.

So go visit the San Diego Air & Space Museum . . . and look up!

Restoring native habitat by Paradise Creek.

I met a cool guy today!

As I walked along the Paradise Creek Trail in National City, I noticed someone in an orange vest moving about near the San Diego Bay National Wildlife Refuge, in a shrubby area at the edge of Paradise Marsh. He was working just off the roadside trail, a little north of the Pier 32 Marina. I had to ask what he was up to.

I had met Rob of Tierra Data. His company is working with the Port of San Diego to restore habitat by removing Acacia cyclops, also called coastal wattle. He was using super precise GPS to mark where he found living stumps. The stumps need to be effectively removed.

Acacia cyclops is native to Australia. Like eucalyptus trees, it thrives in San Diego’s similar climate. The plant has invaded parts of California, growing in fragile wetland habitats and among riparian communities.

I asked Rob how he recognizes which stumps belong to Acacia cyclops. He explained how seed pods lying in the soil around the stump allow for identification.

I’m so glad I paused to talk for a moment or two. Rob was pleased to explain his activity. (And he described birds he has seen and studied, too!)

There’s always more to learn!

Daguerreotypes in San Diego on World Photography Day!

Today is World Photography Day. I didn’t realize that until I met a photographer in Balboa Park, aiming an interesting camera at the Spreckels Organ Pavilion.

What sort of camera is that? I asked. Anton told me he was using a daguerreotype camera. He was utilizing photographic technology that was revolutionary and popular in the mid-1800s!

Daguerreotype was the first publicly available photographic process, producing the black and white images you’ve probably seen in historical exhibits or documentaries.

Anton was using a silver plate and briefly described the process, all of which was far over my head. Here’s the Wikipedia page concerning daguerrotype photography.

If you’d like to check out Anton’s fascinating The Photo Palace blog, here it is. His site features a variety of cool photographs he has taken.

Anton explains in his blog: Working with analog photographic methods, with concentration on daguerreotype and wet plate collodion methods, Photo Palace offers original art, commissions on location and in studio, as well as workshops, magic lantern shows, and other interactive programs.
