Here are a few clips from Hallowharrie 09 in Uwharrie National Forest in North Carolina.
The ledges my wife filmed are the hardest obstacles in the park, if you search youtube, there are a ton of videos. I was lucky (as usual) and made it up both ledges with no strap, and on a bald spare tire. I ripped open one of my nice new AT2s about 1 hour before these videos, changed the tire on the trail with my airbag, which came in handy later on that day for a Rodeo that was pinned on some rocks and strapping him out would not work. Yippee for my gadgets!!!

Here is a good shot of the bumper....it worked like a champ, I pushed up on poser rock, full weight on the bumper and drove up it, and back down, the bumper held, no bending, no deformation...success

I will add a few more videos, they are a couple of minutes long, so youtube is still processing.
