Moo - if you go here... there are some links to the tracks in your area... you would be either District 11 or 12 (or both if you want)
http://www.ama-cycle.org/index.asp
And every District is different as far as numbers go... D-17 (IL) lets you "pick" your number and you get it if it's available for your class, D-15 (IN) wants you to run the last 2 or 3 digits of your AMA number, and others just assign you a number.
And some tracks have races that aren't even considered district races (like in TN) and other places (like FL) have races that aren't even AMA sanctioned (they're a part of different organizations like the MRA) ...
So - to make a long story short - you can just throw any number on your bike and sign up for whatever you need to at your first race (AMA & District) or follow a few track links near you and talk to the promoter about your specific district.
Good luck... prepare to get hooked on racing!!!
