Congrats on your hunt Bigthree,
I would love to see a pic of your bull!
The advice given so far is dead on! I hunted it last year with my bow and I can promise you there will not be a lack of bulls to choose from. The catch is can you get close enough to them to kill one. Don't over look waterhole/wallows. Try ambushing one too. With the early start date, these will be great choices. Calling will be less productive but certainly not ineffective. Get off the roads and main trails. If you are not into elk, move. That is a huge unit and it is absolutely full of elk. My wife got really lucky and drew a Muzzleloader tag this year. We will be up there looking around. Hopefully a few quality bulls make it till then! Good luck to you. Be ready to hunt your butt off and have the hunt of a lifetime!
