Plaza de Panama in Balboa Park used to be a parking lot for cars until a few years ago. Now it is for people of all ages and abilities to enjoy. Select museums are free on Tuesdays if you are a resident in San Diego.

I had a Burritto from a Taco Truck and got a drink from Messhuggah Shack at The Quartyard in East Village. I stayed there for two hours. I played chess, talked to other dog owners at the small dog park, played giant Jenga, tossed bean bags, listened to the surround sound music that masked downtown traffic.
