I think it would be great to bring in one of those giant jumbotrons that go on the back of a truck, and park it at a prime tailgate spot. When the game starts put the game on the jumbotron and encourage everyone to stay in the parking lot and watch.... Empty seats and a crowd of fans watching TV in the parking lot.. talk about national media coverage....
And for a banner:
