BIGGCATT88,
If you've never been in the Grey's River region, you might want to think about hiring a guide. The rugged part isn't that bad if you're used to high elevation, rugged hunts. It's getting a huge muley out and back to your vehicle that might cause you to use words that you never knew were in your vocabulary.
I can be stubborn. It took me two backpacking trips way back into that region before I was able to confirm what I knew before I began my first Grey's River attempt: I shoulda hired a guide.
One more small detail: keep an eye out for bull moose. I stood motionless for a long time while one stared me down, and he wasn't in a socializin' mood. Thank God he took his cow and meandered to wherever bull moose want to meander. If he had other ideas, I'd still be up there somewhere. For huge animals, they are sneaky. I didn't hear 'em comin', & my heart was poundin' too loudly to hear 'em goin'!
Best of luck.
