Surprises on list of "gayest cities in America"

San Francisco - We all know San Francisco is the gayest city in America.

But is Columbus, Ohio really gayer than Miami or Los Angeles?

A demographer at UCLA says that small towns like Portland (Maine and Oregon) and Springfield, Mass. have a far greater "Gay/Lesbian" index than some big cities like New York.

Chicago doesn't make the top 20.
