We can shovel some dirt on your car after each race if that will help ya.
Slightly off topic.... We are also doing an enduro race up here on Sunday, September 18th. Here is the link to the flyer:

We did this last year and it was a blast. Plus, you get pizza for lunch as part of your entry fee. See the flyer for details. It's a great way to start the indoor racing season. <Indoor carper racing that is>
