I rode there last year over Labor Day. Rode the North course on Saturday, the South course on Sunday. Was supposed to ride the full course on Monday, but it was raining when we got up in the morning, so we headed back to Georgia.
Overall, a fun track. I was really concerned initially that it was going to be pancake-flat, but they've sculpted a few hills into it, which is good.
North course, to my mind, was a little more technical. It's also a bit shorter. Not a ton of straight fast, but definitely a blast.
South course was faster, less technical. For some reason I couldn't get a good line on turn one, but other than that, I felt pretty good about it overall. Also, I think it's flatter, but that's an impression.
