In many areas out here in Elk Country landowners will let you hunt their land for a "trespassing fee". It is usually a hell of a lot more than $150.00 a day! Sounds to me like a very good deal. Especially if you get to hunt private ground. Did the outfitter mention success rates? How much Elk hunting experience do you have? Are they at least going to help you pack it out and get it to the processor? That would be the least they should do in addition to 3 squares and a cot.
Good luck . . . Elk hunting is a wonderfull way to spend a few days in the mountains every fall.
