If anyone is even thinking about doing this event.... DO IT!!!!
If you've never been to Grissom air force base, you're missing out on a large concrete (I've heard it called the grippiest site in America) lot with nothing to hit. Course should be fast and flowing, totally different from the gravelly nature of the Kruse or Verizon lots. Heck, the national tour is hosted there!!
Its not too long of a drive, my house is 1 hour 15 min away. And if you like it, you can come back the following weekend for the GASS divisional event and see a bunch of nationally setup car haul serious a$$!
Just my .02 cents....
