The nearest beach to my home is The Aquatic Park. Here's a view today from my favorite patch i call Hyde Street Beach as it is just next to Hyde Street Pier. It's in the middle of a lot of bustle, but so little used. The abandoned boat does lend it a certain Lost quality, doesn't it?
San Francisco's North Shore from Hyde Street Pier to The Presidio is the city's most glorious edge, though better beaches are found on the Northwest side. I prefer The North Shore, Chrissy Field & Lagoon if i have a car, but The Aquatic Park is the one within walking distance. I feel lucky for that.
