Crissy Field
One of my happiest experiences in the Bay Area was the reopening of Crissy Field as a national park. They were handing out free kites. I flew mine for a couple hours of pure, carefree, unalloyed fun, then gave it to three kids who had arrived too late to get one.
Crissy field is one of the windiest places in San Francisco, and ideal for flying kites. I am not sure who thought it would be a good place to build an airfield, though…
