Chris, welcome to the board!
All, another idea for the meet... maybe schedule it around the upcoming NASA / BMW club racing event at PIR on 3-4 October... could do a drive from that point and go explore west, and maybe spend a couple hours at the track watching racing, time trialing, drifting etc... and here's link to the registration discussion if you want to drive your car at the track... instructors are free
October 3-4 w/ BMWCCA @ Phoenix International Raceway - NASA AZ
