No, that isn’t really a ghost. At least, I don’t think so!
This cool photo shows a fellow dressed like an early resident of San Diego. I spotted him walking through Old Town first thing in the morning, before the daily throng of tourists began to filter in.
You can walk with a costumed tour guide and learn all about the early history of San Diego, back when the tiny, seldom-visited town belonged to Spain, then Mexico, then finally the United States. The hour-long walking tour is free and begins at the Robinson-Rose House at the northwest end of the large central plaza. Several historic buildings and interesting museums are visited during the leisurely tour. Whether or not you see a ghost might depend on your imagination! The walking tours begin at 11 am and 2 pm.
