Yup - rode there in summer of '99 and it was awesome!! Out of the 20-something tracks I've been to... it was in my top 5. But I have heard that they've changed it a lot since then. Basically, I think they added more jumps - which should make it even better.
It's a pretty long, natural terrain track that they can run in several different directions... www.knobbyhill.com should answer the rest of your questions.
