When I was in college I had a badass 20" Hoffman, when he first started making bikes. It was amazing, like a prototype or something I was able to acquire when I was wrenching at a shop in Tucson.
I left it ulocked one night outside my place, came out, an the bars and seat/post were gone. Went in to get my key to bring it inside, came back out, wheels and fork were gone. Then I went in to call the police, and when I came back out, the whole bike was missing.
So I filed a report, and 3 weeks later I was doing community service at the Tucson zoo and saw some effing punk cruising on my now *******ized 20". He was a 13 year old pre pubescent boy with his fishing pole. I caught him gave him the option to hand it over and walk away, but he kept insisting "he bought it in california", so I had him arrested.
At the end of the day, all the high end parts were sold and the kid replaced them with bull**** wall mart crap, and even then, the bike was returned to me frame only with a massive dent in the top tube from popping the u-lock. I then turned around and sold it for $300 to sucker I knew.
Just keep your head up dude, it'll probably turn up.
