Been going every year since the mid 80's....there really is nothing like it. The speeds have to be seen to be believed, the riders who take it on deserve all the admiration they get.
The jump featured, where multiple bikes wheelie towards the camera, is called Ballacrye, it's about half way around the circuit, and is preceeded by a blind, but near flat out left hander. The fast men will be pulling those wheelies at 150 mph !
If you are into bike sport.....go !
