You get paddock bashing! It's the best motorsport from Australia and New Zealand that has to come to the States.
Basically, paddock bashing is when you and your buddies have access to a field (though a dirt course like this "Mount Horrible" ain't bad) and a bunch of junky old Holdens, Nissans or whatever. I think you just race and crash until someone decides there's a winner or only one car is left standing. Truth be told, I'm not sure there are rules for paddock bashing.
Readers from the upside-down side of the world, please feel free to weigh in on paddock bashing and educate us American'ts.
