Well I am only in Boston... sounds like there's a bit less worry for bikes here than in NYC. I havn't had any problems but I do think I wouldn't mind getting a mini for my rear wheel. It seems slightly pointless though, since once they get the main lock off they can just throw it in a car and pick it at their leisure, but I guess it looks more intimidating. I don't worry about my saddle because it's a cheapo and I can get another cheapo easy.
