This is my 2009 Brooks Range Dall. We packed (hiked) in 9 miles to to where we set up a spike camp. I harvested mine on the 4th day of hunting. The day I harvested mine, we gained 4600' of elevation less than a mile from camp. That is where the term "sucking air" comes from.
Sheep hunting changes you. There is nothing else like it.
I hope you can find a way to do it before a 10 year wait.
