I did thay as well, i just wanted to see how much i could get for my bike. I wont do it again because you get people who say loads and then it makes you fell as though its worth selling. Dot do it !
Ive been there and not ridden and it is amazing, open and in the woods a little bit aswell.
edit: Ive just watched the video and I noticed that they have got rid of the jeep thing.
I think the best thing to do is just go on it. Its better if you dont know what the ride goes like because then once your on you cant go back. Just go for it.
