In northern/central New Mexico - all gay bars and clubs closed some years ago in Santa Fe (absolutely none here....everything is supposedly "gay friendly" or "gay owned" -- but there is no place to congregate except maybe a Friday night gay men's happy hour at Rainbow Vision (an originally gay-retirement community complex here in Santa Fe, which opened a couple of years ago) at a teeny bar they have. Sometimes there's a feeble drag show...
In Albuquerque, the biggest city in NM (some 450,000 people and with UNV college population too) , ALL the bars but one (The Sidewinder) have closed over the past many months. ALL of them! And Pride Gym, which I hear turned into a bath house on Friday/Saturday nights, closed down some months ago, too. So what's a diva to do? lol
Also, reported to me (I'm an ex-San Francisco resident), so many of the old iconic gay bars in San Francisco have been sold and bought out, turned into homogenous mixed-clientele bars. Perhaps this reflects that gays are everywhere, no longer clustered in gay communities like the Castro, old Polk street, etc.
Well, I'd say all the reasons you guys have given could be the cause...although the economy wasn't tanking back when the closures were all happening here.
A large part of the population in Santa Fe is already-partnered people - so maybe they don't go out to bars any more and don't care that there aren't any exclusively gay venues. The younger ones maybe can't get in to drink anyway. The rest of us singles have turned to the Internet in frustration -- or rely on getting introduced socially to friends of friends, etc. and go from there.
