It's hard to say how big the turn out will be as far as actual racers, past events struggled to see 30 machines. We seem to have a lot more support and intrest this year so it should be interesting. The will always be hundreds of other people enjoying the park!
The knobbie class is where it a at!!
I try to keep the prices as fair as I can, but it's hard to make it all happen for free, I need some sponsors.
I'll add this disclaimer now just in case:
They are gearing up to shoot a reality TV show there around the time of the first race so it is possible there will be more than just camera phones recording the event. I'm sure you will be able to opt out if that bothers you.
