hey, there is not really a sign up page. It is open to as many peeps as show up i believe. When you get there you fill out a form, they do a quick tech inspection, and its $20 to run as many runs as the day allows. We probably will meet for breakfast around 6:00, get to the track around 7;00-7:30.
I did post up to an old thread
http://www.camaro5.com/forums/showthread.php?t=74863 to see if anyone else is interested. And there is another thread post #14 that has more info.
