We have no idea. All we know is that tourists do what they do, because they are told to and some of it looks like it actually is fun. In the name of science, tourists and good nature or something, an adventure was taken on for you: The Bay Quackers tour!
After buying a smoking hot red fanny pack for $1.99 at the Goodwill, and from one of those stores on “Hey, all these stores look the same” Fisherman Wharf’s Jefferson street, a $.99 blindingly yellow polyurethane Fisherman's Wharf jacket and an Alcatraz t-shirt in which the wearer's head is the head of the Alcatraz cartoon character (how clever!), we were ready. Amidst the tourists (not only tourists, but Fisherman's Wharf tourists), we totally stuck out, and that is no easy feat.
