so this is my second year attending, my first time for more than one day. i can't afford a hotel, so i'm commuting each day, and i need to know the street address for parking garages that won't charge for parking, or will not charge much. previously, i had parked at a meter, and while the meter was not expensive, having to put in quarters every two hours was annoying. i'd prefer to find a parking garage, but lacking that i can still do meters. any that run for more than two hours?
