In a city as closely packed as San Francisco (it's the second most densely populated city in America), it's always a revelation to come across some forgotten little place with no one around. This is the end of 23rd Street near the DHL warehouse and the, now closed, P.G.& E. plant. Heaps of atmosphere and a great place to leave a body. The waterfront was lined with this sort of place 30 years ago, before our city planners realized that people like, really like, to be near the water. There's a little, scruffy park across this inlet called Warm Water Cove Park. I'm not brave enough to investigate the temperature of the water but I'll check out the park soon.
