Portland has a ridiculous amount of fixies. I'd say that in some areas of the city the only bikes i see are one gears. That said, I'm the only one of my fat drunken frat dude circle of friends who actually gives a **** about exercise, much less cycling so I don't really know what the Portland scene is like. I wouldn't mind meeting some local peeps though, especially when I consider how much fun I have drinking and riding on my bike alone, much less with a large group of hooligans.
