Just spent a week camping there. Lots of nice bulls and a few spikes. Talked to a local guy and between what he said and my observations, .....go find steep hillsides where the bed and set up. When I say steep I mean STEEP! They like looking down at you. That's what I saw. Ran into one young two point bull who kept buggling every morning and wandered in and around our camp all the time. Not afraid of humans...yet!
Good luck! Build up the legs or find the routes and set up on them.
