It was a hot day in San Francisco for hanging out on the street during the annual Park(ing) Day, which happens worldwide. Good thing there was plenty of foliage to soak up the CO2 in many of the spots, many of which were spotted downtown and in the Mission. It was duly noted that San Francisco has plenty of green spaces when you seek them out, but it's definitely refreshing to see a small oasis here and there in the middle of such urban settings.
