Hopefully! A friend of mine had his Cannondale mountain bike stolen, and nigh on a year later, he was driving down a road near the university and saw a guy riding his bike! (He had a pretty unique set of aftermarket parts on it, which is how he recognized it.) It wasn't the thief (it was a student who'd just bought it from someone recently), but he did end up getting the bike back. So, you never know!
