I agree that most bike nights equal squidies, cops, attitudes, and an accident waiting to happen.
That being said. I just moved from the SF YahArea, to North Cali Sacatamatoes, a few years ago, and I find that having NO bike nights whatsoever make me a bit homesick, and make me realize that along with the squidies, and bad attitudes also came the hotties, in thongs and heels that were only looking for something that they could ride hard.
All in all, I guess bike nights aren't that bad, and I sure wouldn't mind hooking up with some new people to go riding with in the canyons, and or a Ducati Groupie for the night.
