Yachts bob at their moorings, satisfied-looking folks jog along the Marina Green, and multimillion-dollar homes overlook the bay in the picturesque, if somewhat sterile, Marina neighborhood. Does it all seem a bit too perfect? Well, it got this way after the hard knock of Loma Prieta—the current pretty face was put on after hundreds of homes collapsed in the 1989 earthquake. Just west of this waterfront area is a more
natural beauty: the Presidio. Once a military base, this beautiful, sprawling park is mostly green space, with hills, woods, and the marshlands of Crissy Field.
