I happened to be in San Francisco during a rare run of 90+ degree days. In this city where air conditioning is rarer than Republicans, a superheated weekday is almost the equivalent of a Midwestern snow day. Computer servers were crashing, commuter trains were backing up, and at least one man walked downtown streets muttering, "It's too hot...too hot...we're screwed." But at 4:00 on Friday afternoon, people poured from stuffy old office buildings and sweltering Victorian flats to revel in the breeze and views of city oases like this, the Mission District's Dolores Park.
