I stayed there a few years ago. They have a military display (Tanks, planes, etc.) of sorts as you pass the office. It was Memorial Day weekend and they had some displays set up with guys dressed in period correct military uniforms. They then put on mock battles, which was pretty cool to watch.
They also have a huge field where people come out to fly R/C planes. There must have been 30 to 40 R/C planes there. It was cool to watch them fly and perform stunts.
We had a great time.
I've always told my wife, who is a Ga native, that if I ever move from Ga, it will be because of the dag nabbit gnats.
