I spent a lot of time in that unit last year.. although I was unsuccessful in my deer hunt, here are some takeaways.
Get away from the roads. 90% of the hunters in this unit are near roads, and you’ll see very few deer. I think the packing in method will serve you well
Train for elevation. The big animals like to hang out up high, and it’s rough on your lungs.
Carry a sidearm. I saw a bear and mountain lion up there last year, so be careful.

P.S it’s some of the prettiest country I’ve ever seen. Enjoy!
