I was there the whole weekend. There were so many people, I only ran into about about half a dozen friends out of 20 that were there. It was like someone kicked an ant bed. The good news was that everyone seemed to congregate at the river and mudhole. That made the rock trails near vacant.
I haven't heard the official count, but judging from past experience I would say there were at least 400 trail vehicles and 1200 people in attendance.
I had a great time and despite all the wheelies and abuse I put ole Blue through, the only damage sustained was a broken radio antenna.
The trail that you have in the pic with the camo Jeep is Whiskey Springs. I got a golf clap from the crowd for pulling some air through the midsection where you have to bulldog it between two big rocks. I wish I could see it on tape. It felt like the front end was 2 feet off the ground.
