I really like the champion card idea, where someone can pick a weekend and they get free gate pass and race entry.
Other ideas floating around upstairs are:
Having three prize tables - with different level prizes to go with your award. For example, $100 items for 1st, $50 items for 2nd-3rd, $25 items for 4th-5th.
Every rider that's eligible for an award gets an OMA gift bag at registration.
In terms of grand prizes it might be tough to top last year. I don't want to show my hand here with these ideas, so I wont post too much of what's up my sleeve, but I will say I would like to giveaway a Honda Generator and possibly an electric power washer as far as entry level grand prizes. Sx tickets again would be cool. Go Pros will never be out...especially with the Hero 4 hitting the streets. What about Grand Prizes? What sort of big ticket items?
