Driving home this evening, about 10pm - guy flags me down, presumably because of the 4 bike racks on the roof of the car. He's found a decent mountain bike in the middle of the road. He's pulled it to the side, but isn't local (and has a little car), and doesn't just want to leave it there.
So, I've taken the bike home. Will call the Police in the morning, and the Bike Factory in Chester (label on bike) and try to reunite the bike with its owner. However, if anyone can describe said bike in detail, send me a mail. I'm assuming it's fallen off someone's bike rack.
