I'm planning something similar this year with a hunting buddy. I decided to make it a mule deer trip before elk season simply for the fact that I didn't want to bite off to much at once. Having two guys with a mule deer down way back is a lot different than an elk. What ever you chose will be a blast, just be ready as much as you can, especially with meat handling. There are a lot of guys that I have read on here that hang there meat down by a cool stream in the back country for days without trouble. Learn how to d-bone, learn the tricks to cooling / proper storage etc and you will be fine. Have your friends lined up & maybe make another backup plan if they are busy. Have fun ! Mike
