I feel safe enough in Montreal with a box wrench and a U-lock in easy reach, but now that I think of it if I were to be riding all-over-everywhere-everyday in downtown B-More, I'd probably ride strapped. I saw something about a .22 that was made for runners and cyclists and such. Know anything about that one? Real easy to conceal, as I remember, but I feel it'd be kind of like bringing a knife to a gunfight in some parts of town...
