Is their any monetary awards for the best two to four winning cars in each of their classes? If not, why not?
No money involved with the winners. The event doesn't pay, so it keeps the atmosphere low key. It's hard to explain the gains one gets out of these events. The money would mean nothing, after a short time, but the experience, and friendships gained are priceless, and last a life time. Until you experience it in person, some just don't get it. Maybe never will. Those that have, it becomes an addiction.
