Well, I thought we covered everything but, I just remembered this little note for first timers. DONT EVEN THINK ABOUT IT IF YOU HAVE BEEN DRINKING OR ARE HUNGOVER, OR UNDER THE INFLUENCE OF ANY KIND OF DRUG THAT CAN SLOW YOUR REACTIONS. It takes 100 percent of your concentration. If you break a axle, blow a tire, or find a greasy spot, you need to be able to react. And one more thing. If you blow something up, get it on the shoulder as quick as you safely can. I've seen people blow them up and let it roll down the track surface, causing a hell of a mess and making it dangerous for everybody after them.
