Do you take a shower in a fullface helmet? Cuz a bunch of peolpe crack their skull by slipping in the bathtub, and a cracked skull is worse than a stolen bike (or is it?... I think if you die it is).
Anyway, any reasonable person will try and limit the chances of getting their bike stolen w/ a number of methods, (buying 1 or 2 good locks and using them cleverly being some of the most important), instead of walking around with a bike inside the corner store like a fool. Which brings us to why this thread is relevant.
