We have more cars at my house currently than room for them. The house next to us was vacant, so it wasn't a problem because we could just park in front of their house and in that driveway for a while. Then the house finally got put on the market, so the driveway was out. Now it's bought and the front of that house is out. I'm really a bit concerned because the next day I go into work, I'll literally have nowhere to park when I get home. We have no neighbors that won't get mad if I park in front of their house.

Edit: I do get a little cranky if I ever establish a "spot" and someone take it though. Parking isn't a problem because I never really establish a spot, but if a general area is full of cars at work, I end up not happy.
