I learned the hard way not to leave mine in the kitchen, leaning up against the wall, where it could be seen from the back door. Went away for a long weekend last November and came home to a kicked in back door and a missing bike. My new bike (no thanks to my insurance deductible) stays in the house, not the garage, but not where anyone can peer in and see it. When I go out of town without it, I lock it to my iron staircase and remember to set my alarm system. I'm gonna make the #*()@&()@'s work for it next time.
