I park my bike in the dining room at home, and in my cube at work.
I park my Jeep in the spot closest to my neighbour's apartment and I leave it there all week. (Mostly I park in that spot just to annoy my next door neighbour who gets mad when he has to walk an extra 2 or 3 parking spots to get to his car every day. Yeah, I'm an a-hole like that; but he started it by parking in the handicapped spot to use it as a loading zone, and then telling my g/f (who has an HC tag) to park in an open spot way across the lot when she told him to move his car.)

I don't usually park on any sidewalks (although I did partially, for loading purposes when I was moving out of my old apartment.) My personal favourite parking job, and I wish I took pictures of it, was when I went out 4-wheeling in the snow with my friends from the local off-roading club. Plows had piled snow up in the parking lane about 3 or 4 feet high in front of the joint we were going to for lunch. We all drove up on top of the snow heap and parked there. We even dug out the parking meters and fed them so it was as close to legal as we could get.
