Orginally there was talk of a bet... $50 may ward some people off, but say a challenge race where the racers throw in a hat $10 per racer/ per class,
winnings for each class: $20 for TQ, $10 for 3rd, $20 for 2nd, winner takes the rest (this price breakdown assumes more than 7 people enter the challenge race though...)
OOOOOORRRRRRR
Just have a normal race day with all kinds of Nor/So Cal smack talking going on. Then end the event with a 5 minute race backwards. 10 bucks to run, the winner buys the drinks!
