I watched it on TV with Jnr FD.
I had wondered about going, however I had always assumed that you are not allowed in unless you can whoop and holler like some dude, make sick hand gestures, or for that matter carry a chainsaw (wtf ?!?)
Best bits for me were the bits of natural riding. Most DH course are 99% man made but at least this did have some natural sections that looked bloody ridiculously hard !
