Santa Rosa, the second-gayest city in the U.S., is just an hour north of San Francisco—and, like the Golden Gate City, the queer community there is mostly male (63 percent). Unlike San Francisco, though, it's fairly old. The median age: 39.3. This makes Santa Rosa the 292nd youngest gay population in the country.
