In the town of Atwater in California's central valley, there used to be Castle Air Force Base. After the base closed, Castle Air Museum was opened, with a fine collection of old military airplanes. This one's a Boeing B-17B "Flying Fortress" bomber from World War II. For more info on the museum, check out www.elite.net/castle-air. (The museum has a surprisingly good snack bar, too, for a simple hamburgers-and-hot-dogs type place.)
