My dad had the early tag two years ago. We started above Power Lake, saw tons of sign, did get a fleeting look at a bull but they were very nocturnal. We also saw every other tag holder, none of whom had seen anything. We moved to the Tacoma Road and shot his bull in one of the new clearcuts on the road that heads up Calispell.
That year the entire Tacoma drainage and northern end of the unit was being logged like crazy. Probably some great places to look for one there now.
From other tag holders we befriended we heard of one bull taken three miles beyond a closed road above power lake, one on the power cut on Winchester Creek and another on the backside of the ski resort.
My father is older and we mostly drove. Tried calling to no avail, and he is an experienced moose caller.
