Great tag! You'll have a blast and will see a lot of bulls. And when I say a lot, that's an understatement. Getting your bull out of there is just plain work, and lots of it. This was already said, but you'll need some good help that's readily available.
On all my trips in there for blacktail and photography, I can pack in and stay 4-days. For the most part, there's plenty of water coming out of the rocks and plenty of natural seeps. You just need to mark the areas and save them for reference. These areas also assist in keeping your meat cooler and allow you an extra day to get it out.
I've only packed out deer from there and only helped pack out a friends bull a few years back. The few bucks I did get, along with camp took me (2) trips. We packed out my friends bull and his camp with (5) people in 1-trip, but it could be done with (4), but the packs will be pretty heavy.
Have fun and congratulations!!!
