The other night, my wife and I went to downtown San Diego for dinner and to goto a dueling piano bar (we left the little one with my parents). Parking, of course, is a nightmare, and after driving around for a little bit (my wife said I wasn’t aggressive enough in finding parking), I saw a spot in a yellow zone and zipped into it. I couldn’t recall what the regulations are regarding yellow zones after 6 pm, so I pulled out an iPhone and searched. I found a few references to parking in yellow zones and then stumbled upon a document from the city. With the information in my hand, I was sure that I could park in the yellow zone. We had one of the best parking spots in downtown; I’ll have to remember that for next time.
