I'll be there no matter what, but there has to be food, booze, shelter, and some kind of entertainment for the casual bandwagon types in the parking lot. If it were me, I'd go back to an Albi parking lot style setup. Put up a big tent with food and beer inside, as well as some screens with a couple college games on. Outside, I'd rent one of those big inflatable screens to show games as well. Take a few of the portable bleachers from the practice field and park them in front of the screen for folks to sit on. Keep it simple, but give the people what they want. Football games, food, booze, heat and shelter. It doesn't have to be complicated.
