No wonder your fu*ked up. MDRA stands for midwest dirt racing assoitation for out west. AHRMA is vintage bike racing. Do you need an AMA for your track? If you do, get one, then show up race day with a parent and your gear and bike and sign up for schoolboy C class. They will need to see your AMA card if so, and your parents will have to sign off for you. Thats it, easy as that. Allthough, how much track experiance do you have? This is what I say, 6mo. to learn the track life, 6mo. to get the right feel for the jumps and stuff, and 6 mo. to get fast. Then you race like a pro.
