Elk/deer big game combo cost me $1,300 as a MT NR last fall. In the Bob, the muleys and elk frequented the same areas during early rifle season (9/15-9/22). However, bulls were the priority. We often saw does while calling for bulls, but it was bull/buck only in the unit so we had to pass. We did go after one trophy buck a guy spotted in the dark timber on the way to our glassing spot, but he disappeared.
As a NR, to maximize my opportunity of taking an animal home, I would always recommend buying tags for animals in season and in the same areas. I had a bear tag with me as well, but we never got a shot at one.
