Still there have been plenty of times that I locked up my bike outside of a store or restaurant and I always worried about it until I had it in my sight.
The article over at London cyclist listed some interesting statistics the most interesting was that 2/3 of people give up cycling after their bike was stolen. That seem like a very large number. I don't know what I would do if BOB got stolen but I hope the answer to that question isn't stop riding.
