my son's miyata fixie was cut free from its chain and stolen. A few weeks later (after we bought him a new bike) his brother saw a kid riding the bike and eventually caught up with him and informed him that the bike was stolen. My son later went to the kid's house (a 20 year old kid, sorry) and gave him 20 bucks for the bike. the kid said he found it outside the dormitory. So it pays to be alert, sometimes it happens!
