The classic Spruce Street Suspension Bridge is located just west of First Avenue and crosses narrow Kate Sessions Canyon. It’s an amazing, breathtaking 375 feet long! Steel cables support a gently swaying passage through and above treetops, and a walk along its length feels like a small, romantic adventure. The bridge was designed by Edwin Capps, the city engineer who was also responsible for plans to dredge San Diego Bay, and who would go on to be elected mayor. (It was Capps who hired the rainmaker Charley Hatfield, the central character in one of San Diego’s most legendary tales! Perhaps I’ll blog about it one day…)
Built in 1912, the purpose of the Spruce Street Suspension Bridge was to provide easy access for those who lived to the west to trolley lines on Fourth and Fifth Avenue.
The Spruce Street steel cable suspension footbridge, engineered by Edwin Capps, was erected in 1912.Wouldn’t you like to walk out on this bridge?The swaying suspension bridge is a unique, historic structure just north of downtown San Diego.Lots of people love this hidden bridge. You feel like you’re crossing through a wilderness of treetops!Bicyclists enjoy a dirt trail 70 feet below.Boy sits thoughtfully on the Spruce Street Suspension Bridge in Bankers Hill.

Kids learn about electronics by combining fun pieces from a kit, creating circuits.
Today I checked out a truly amazing event! Expo Day capped off the week-long San Diego Festival of Science and Engineering (formerly known as the San Diego Science Festival), and brought out thousands of families and kids, eager to learn about science. STEM, which stands for Science, Technology, Engineering and Math education, was Expo Day’s principal focus. The seventh annual event nearly burst the seams of downtown’s big Petco Park stadium. There were so many cool exhibits, so much stuff to see, I only managed to experience about half of it! My poor old brain nearly exploded!
Here is a bit of what I saw!
Exhibitor map for the huge Expo Day, concluding event of the San Diego Festival for Science and Engineering.Lots of folks inside Petco Park (baseball stadium of the San Diego Padres) learn about science.This kid is way more interested in a map to cool science stuff than boring bags of cotton candy!A robot was moving mysteriously about, amusing people who were just walking along the concourse.Group demonstrates the structure of some common molecules.The STEM event focused on Science, Technology, Engineering and Math education.Investigating organisms one might find in a mud flat.This balloon soon rose on a column of air and floated out of the tube!Young inventors assemble unique creations using all sorts of ordinary materials.Understanding genetic attributes using Boolean logic. Sounds complicated!Youth would attempt to break a Guinness World Record at Second Hour of Code mass coding event led by a Microsoft professional.I’ve never seen so many hands on experiments in one place!Don’t mess with this guy. He’s a super cool scientist dude!Kids test out non-Newtonian fluids which seem to harden like rubber when struck.Young scientific explorers are shown how to build their own spectroscope! And to think I was confounded by my Etch A Sketch!Test your own mental cognition and speak these colors really fast for yourself!Oh, man! Check this weird elephant out! I love optical illusions!This fancy lab aquarium acts as a flume, used to test the motion of fish and their muscular development.Pointing out a butterfly in a carefully classified collection.Wow! These youngsters are building DNA models! That’s way beyond me!Learning how smoking exposes people to all sorts of toxic chemicals.Girl learns about gyroscopes and angular momentum with a spinning bicycle tire.Some students built cool models of futuristic cities.Awesome robots were all over the place!People were jumping about as this robot dashed about scooping stuff up.This robot participates in the Lego League, trying to score points on an unusual course.This is a mechanical, computerized Rubik’s Cube solver that detects color.Looking down into Petco Park’s Power Alley, where more STEM exhibits were located.Lots of animal life on display included this beautiful long-nosed snake.Lady demonstrates how bio fuels are refined using filtration.Christmas lights helped to teach about energy conservation.Tens of thousands turned out for the big San Diego Festival of Science and Engineering Expo Day.Many businesses were showing their products, discoveries and technological advances.AirZooka vortex generator shoots circular pulse of air at the shimmer wall!This automated machine helps prepare lab samples in medical facilities.Kids left notes on a wall with their bright ideas.Planting some tomato seeds, to watch them sprout and grow at home!More kids making complex molecules with colored marshmallows! I guess they’ll be future scientists!Some art was being created to accompany all the science and technology stuff.This guy uses electromagnetism to launch cans skyward and splatter cucumbers!Petco’s sunny Park at the Park was jammed with families enthused by education.Demonstrating maglev (magnetic levitation) using eddy currents.Young people write down what they like about science!Young astronomers duplicate the colors of an enhanced surface image of asteroid Vesta.This NASA inflatable is the actual size of the Curiosity rover now on Mars.Everyone is fascinated by a cool NASA photograph of the surface of Mars.A member of the next generation lays his hands on our planet.
