Here is one such method... Paint Yourself in you school colors to show your spirit and walk though the tailgating region in front of the 90K seat stadium.
Just sharing some experience from an awful awful game (42 to 0 : lose). I know some of you have not gotten here yet, but one day this may be usefull....
Step 1: Paint Your Car and Wear a T-shirt
Also demonstrated -- wear your school T-shirt and colors.
Make a sign that says: RIP -
Step 2: Find the Tailgate
To help feel in place, find some of the local beverage and join the heckling of the competition.
