Looking to attend my First DE this year

You need to sign up through the clubs. You might find some you can get into though Motorsportreg.com but generally you will need to become a club member for a nominal fee. The clubs are usually regional so try and find the ones in your area. If you have a track close by and you really get the bug you can get a track membership, but those tend to be rather expensive.

Just some clubs off the top of my head that will let anyone join.

COM
SCMC
SCCA
BMW

They usually divide the running into experience groups, Novice, Intermediate, Experienced. You will have to sign up as a Novice at first and will have an instructor riding with you. Instructors are usually great and help you get comfortable with the track and the correct driving line.

A lot of clubs are having trouble filling the registration sheets at the moment so you might be able to get into some events on fairly short notice. Once you get the bug you'll be driving to all the tracks in a 500 mile range

the clubs are generally cheaper than the for-profit types, like chin motorsports. bmwcca membership doesn't require that you own a bmw (like pca does), and the $40 annual fee is the same as the club discount. i agree with chris- the economy has hurt enrollment in these track days, so i'd bet that any club would be glad to have you run with them. for example, i don't belong to pca, but they have always made me welcome to run in their hpde's, although i know that if the school fills completely, that i would be bumped for a pca member, which hasn't happened yet.
