OK, I did some reviewing of this thread and some map studying.
So far the members who've responded in this thread as wanting to go are from Woodstock, Kennesaw, Cumming, Douglasville, and SW Georgia. Taking the first 4 towns into consideration (sorry 01dynaglide - you're the furthest so it really doesn't matter where we meet in your case) and our destination in mind, it looks like Roswell would be a good meeting place. Just about equal distance for all of us and only about 25 minutes from the show.
There's a Starbucks right off GA400 Exit 7 in Roswell:
Store Details | Starbucks Coffee Company
I was thinking meet there between 8:30 and 9:00 for some java and some conversation and then kickstands up at 9:30 to get to the show when it opens at 10:00.
Let me know what everyone thinks!
