What self-respecting gay man doesn't travel with a change of clothes that includes at least one pair of slacks or jeans?
I was denied access once to a bar for wearing sneakers, but it was some stupid "manly-man's" bar with pool tables and...whatever. They were all a bunch of douchebags, struggling with their own masculinity by denying access to anyone whom they felt wasn't "butch" enough for them.
I go to bars that are so "manly" that you have to stab a biker in the heart just to get it. And there's a 14 drink minimum...because if you can't drink 14 shots in a night, you're just not manly enough.
