Great Idea.
We go to drive-ins anytime we get a chance. There aren't any really nearby where I live but whenever we travel one of the things we always try to do is visit a drive in if there are any in the area. The tickets and the yummy junk food are almost always far cheaper than a regular theatre and the experience in my opinion is better (except for some of their bathrooms my wife doesn't care for them at all :lol
There are actually still quite a few in operation, and actually have been a few new ones reopening in some southern states. Most people when I mention drive-ins say, "Oh I didn't think there were any of them left", but there are plenty. We have been to around 20 drive-ins in the last 7 or 8 years in CA, TX, AZ, NY, VA, FL, ME and two in Canada and all but one was great, the one bad one was run down and in a bad part of the city. Our favorite was one in the little town of Perry, NY. Along with a nice two screen drive-in there was a mini golf course, a great restaraunt/take out and nice playground for the kids.
Anyway drive-ins are great and I strongly recommend everyone go. In fact there are atleast two of them in the Louisville, Kentucky area and that might be something a group of members could do on a night during the meet, you could all park together and hang out and watch a movie. Wish I could go. Many of the drive-ins also have daytime use for yard sales/flea markets, gun shows, and car shows. I bet many of them would allow you to have an ST meet there before the movie.
Finally Drive-Ins rule!!!!
