Fisherman's wharf is regarded as a garish and tacky tourist trap specializing in t-shirt shops, shlocko camera and luggage stores, and questionable restaurants. Despite all the economic clutter, there are real fishermen who harbor their boats and return to the wharf with their catch. This Cadillac is the car one of the fishermen uses to drive to the wharf. He can park it there and not worry about it being vandalized or stolen. The bad guys probably wouldn't be able to start it. The real wharf is there if you want to look for it. There are also some good restaurants, unless you're a trustafarian foodie.
