Race weekends really aren't bad at all crowd wise, you'll run into a few trails being closed off, but that's usually minimal.
As an introduction to DH for some members, I dont think they will appreciate the speed that some riders will be passing by at. For example, begginers using greehorn at the same time as a few expert riders coming off Salvation, not a great combo.
Would I be alright bringing my DJ hardtail? Not a really nice one, but it works for me for now. That's the only bike I have right now. Well, that, and a roadbike soon.
Haha, maybe not the best warning...Utah and Careless Whisper sounds tame enough, but...
Looks like I will rent/borrow in that case.You can ride a hardtail, but you will be limited to the jump line - which is not really that smooth. Alot of the terrain is rock and if you can afford it, rent a DH bike, it will be money well spent. Also I heard that they might not allow bike without disc brakes, I dont know whats on your HT but that is also a consideration.
