Celebrate the American spirit of ingenuity, rebellion and entrepreneurship by embarking on a Prohibition-themed cruise around the Bay. Now in its fifth year, this event offers up breathtaking pyrotechnic views and sells out fast (the four-hour hosted bar is surely a big part of the attraction). With two dance floors, you can exercise your right to choose between Top 40 hits and house music. Deco-era outfits are encouraged, so dust off that zoot suit before you take to the open seas.
