i used to ride a fixed bianchi bobcat mountain bike, which was parked outside of the seward cafe, where i used to work, when i walked up on a drunk from the neighborhood walking away from the bike rack with my bike. he didn't try to get on, just strolled down the alley with it. i chased after him and yelled at him a lot and took my bike back with little difficulty. i think i scared him, which is funny, because if it had come to violence i wouldn't have really known what to do. the point is, when someone is straight up broke, and/or addicted, you could be riding a magna from wal-mart and it won't make a difference. they'll turn around and sell it for twenty bucks, less than you spent on bar tape.
