This seems like a silly question, but I thought better safe than sorry..

Does anyone know of any security risks (or other risks, I suppose) to just leaving my Kryptonite u-lock locked to the rack when I'm not using it?

My lock is big and heavy and it occurred to me today that it is a little dumb that I haul the thing to and from work every day when I could just leave it locked on the bike rack. The bike is stored in my garage when I'm at home and I have lesser locks for quick trips like grocery runs.

Should also mention that I live in a small town with a low crime rate. My office is off the beaten path and there is essentially no visibility of the bike rack from any important roads. If someone were to cut the lock itself just to be a jerk I wouldn't lose any sleep over that. But if someone has an entire weekend to screw around with the lock would they be able to somehow rig it so that they can open it once my bike is attached?

Thanks
