When all the guest parking stalls are full, that means you need to find alternate parking - like on the street. If I came home and found you in my parking stall, I would call the towing company myself. I pay for the priveledge to park and would be very angry if it weren't available. If you live in a house and have guests in your driveway, do you park in your neighbor's driveway? That's life in Minneapolis, you have to pay for parking. Looks like this time you paid with towing charges.
