I live in a town where the college a couple of big computer companies are the primary employers, and you can spot the DUI people really quickly. They ride all kinds of bikes, but tend to wear camouflage or ranching/farming jackets, no helmet but usually a baseball cap with a tobacco/beer/nascar/farm-equipment/muscle-car/Harley Davidson logo, sometimes work or cowboy boots, a big chain wallet, and maybe a belt-knife. They also glare at all of the guys in roadie gear.
I think that a vast majority of these guys are decent and likable guys, but there is a definite class structure here, for some reason. Non techie and college-types find it hard to make enough money to live here, and they harbor a lot of resentment towards "yuppy types". I know a couple of them, and they actually dress like that ONLY when they ride their bikes. It is like a badge of courage, or something.
Why to people spend so much time and effort on something negative like that? I don't get it.
