How did Provincetown, Massachusetts, get to be so “gay, gay, gay,” as the Provincetown Business Guild puts it? Let the locals fill you in. Hear from, among others, the lounge pianist who’s been there 50 years, The Fabulous Dyketones founder, the activist-artist who made a dress out of tampon applicators and the town clerk who married 200 couples in one day. You’ll hear about Portuguese sailors and innkeepers, fine art history, sand-filled cars, mass same-sex weddings in 2004, the dunes, “the dick dock” and more on this documentary-style romp with Out in the Bay host Eric Jansen through what is probably the gayest little city in the world, at least per capita.
