My wife and I just spent two days in Provincetown (Cape Cod MA). It's one place where the bed & breakfasts' guests aren't stuffy couples in their 60s. Most of them did seem to be married, from Massachusetts or California before Prop 8.
It's hot even on the Cape. I noticed most of the gays are wearing cargo shorts (with trimmer Madras shorts also fairly common) and sleeveless T-shirts, so I can continue to wear my fading collection without fear that I am hopelessly out of style.
