Why not hold it in a parking garage. This picture send in by Charles Huntzinger shows what happens at Ohio State:
Tailgating in Parking Garage before an Ohio State Football game. This is the proper use of Garages to build team spirit with lots of Spirit. OSU is currently looking to privatize their campus parking hoping to get 375 million for a 50 year lease. Investors have until November 2nd to qualify. Of course with all the on and off the field problems OSU Football is having I think the price may drop if the tailgate crowd doesn’t park.
