why not set it up for vendor tailgating.. Let say 6-10 vendors set up assigned area's with one being a beer garden and then put out canopy tents for shading. Lastly, allow 6-10 random tailgate spots for the public to bring in their grills/cookers to add to the atmosphere. In the Nov games, put up a several Standing LP heaters to warm the tailgater's. The vendor spots are sold yearly while the public (call them grilling spots) ones are free but only available once per year per family. Draw the public spots randomly and send the spot schedules out accordingly. Vendor and Public spots are setup Friday night to eliminate on campus traffic issues.
