Made a trip down to South Carolina to visit some friends at Moto-Vated Sports Complex a few weeks ago and had a blast. They have a huge facility and if you are in the area I highly suggest riding there. They have a clay/sand track, a huge national style sand track, GP track, turns track, miles of trails and a mud bog. They also have shower houses and clean bathrooms which is nice if you plan on staying for a while like I did. For $20 a day you can ride the entire facility, use their power washer to clean off your equipment and use their showers and restrooms. There was a photographer at their Saturday night practice and she got some pretty cool photos so here's a few. My gopro mount broke off my helmet so I have a short video I'll try to post later but it's really not that great.
