In Minneapolis, there are programs run by both the state DOT and the City of Minneapolis that provide lockers. Here, we sign contracts to rent the lockers for a period of time, and the key is provided at the time the locker contract is submitted. It's a great deal -- $35 for April 1st through the end of November, or $55 year-round. Unfortunately, this year I picked a locker in a location where the drunks/homeless regularly urinate, so the place stinks to high heaven.
