The DE this weekend (1/12 & 13) is sold out. It sold out in a matter of hours. The Drivers Edge is the organization and they are a Dallas, TX based company and run tracks in Texas.
The BMW CCA Lonestar Chapter event is June 7-8. Registration starts on 1/14 and there are some rules around who is allowed first rights to register. Mark Williams can give more details. Let's just say if you aren't a Lonestar Chapter member and haven't driven a BMW CCA DE sponsored or co-sponsored by the Lonestar chapter in the last couple of years, your odds of getting in are very low.
