Wes,

You can meet the east side crew leaving Berge Ford at 8:30am and heading to Costco at Cave Creek and 101 to meet up with another group.
Yes they all park together at the show providing you were able to get into the registration since it is sold out.

I'm not in the show but my wife and I are going! Anyone can go to this, there are PLENTY of cars to see!
We go just to hang out with everyone.
