The Farallon Islands have amazing natural beauty; one can see amazing sights depending on the time of year ... whales swimming by, sea lions, migratory birds, etc., and it is very isolated there and never crowded. Mostly though, I'd like to see how the bus would navigate the 27 miles of open ocean from the western coast of San Francisco to the islands.
