I'm all for wearing whatever color they choose to do a white/green/black out, but unfortunately, The Ralph will NEVER get it out to everyone that has a ticket for that game. In a perfect world, it could just be on the radio and newspaper and everyone would see or hear it. But still, not everyone will go along with it.
The best way for a white out to happen is to hand out shirts, that not everyone will wear, but I'd bet most would. Now, to pay for those shirts. The Relay for Life has T-shirts with major sponsor logos on the back. How many major sponsors does The Ralph have? I'd bet enough to split up that total $ amount into something quite manageable. They could even go to a few other businesses to advertise on the shirts. 25 business logos on the back would work.
Thats my 2 cents on how a white out could work.
