Nope, I'm about 40 minutes from Detroit.

My house hasn't been locked in years either. If I had to lock it, I'd have to pull a bunch of old keys off the wall in the laundry room and figure out if one of them fits the door.

My point is, it's kind of pointless asking on a forum such as this whether people lock their bike or not, unless they can get someone who works in the same building as they do, the advice will probably be useless.
