If you can prove your "veing" a Supra owner I'll consider giving you a free T-shirt. Considering there is no such thing as "veing" a Supra owner the odds of you getting a free T-shirt for proving that are 0.
We count on the T-shirt sales to help us cover a few costs involved in the event. Last year we raised an extra $1000 after everything was paid for and that money was rolled directly into this year's event allowing us to do even more. This year the T-shirt money will be rolled into a special project that we will announce sometime near the end of October. This will be a fundraiser for SILV06. Let's just say FREE FOOD is on the list of things we would love to do with the money we make from this fundraiser.
We try to make things as inexpensive as we can. I've lost track of the number of people that say I should raise the price of the T-shirts and I've said no year after year. The Show-and-Shine is always free and the entry fees for the other activities are passed directly through to the various venues (dyno, drags, poker, road course, etc). We make no money on those activities.
