My wife and I were in the Atlanta area for work and brought along our rigs this past week. We jumped at a few local DZs and found this one to be our least favorite.
The attitude at ASC was geared more to catering the tandems. I've read a lot of reviews and opinions about this DZ and their marketing/business plan, but I wanted to give the place a fair shot myself. Unfortunately I'd have to agree with a number of people about this place, and I really didn't have a whole lot of time there to peal back the onion skin.
The sub-staff (video guys and instructors) were very friendly though. I actually elevated my overall score on ASC based on their interest in the up-jumper crowd.
The landing area was a bit hectic, as people were and landing in multiple directions (not just the swoopers). All in all I would not be surprised if there was an incident in the landing area at some point.
They do have a nice building with a/c in the packing area. And there is a super nice guy that cooks up food that is convenient to buy on-site.
If your in the area visiting, I'd advise checking out a few of the surrounding DZs first. You'll be happier for it.
