Tell hime to concentrate on teh Metaline Falls side of things versus the Kettle Falls side. The moose concentration are much higher. On the Kettle Side you need to be more dialed in. The main cross road out of Metaline I believe is smackout pass. I have ran into good moose on it, Abercrombie, and I believe its baldy Mtn. I think its the 300 road. "chandler meadows" etc. There is good moose habitat in there. then look for those young cuts, or the powerline openings etc, and he'll pick one up. I wish I could be more help. There was a gigantic bull hanging on Tiger pass on the chain of lakes out of Ione. He spent alot of hs time on private ground but there is alot of Nation Forest all around it. They really like those lakes in the sumer. I can't remember if those are in that unit or not. If so, then maybe the lost creek road just past the last lakes. "Stewart Meadows" 4694 0r 4699 road. There is a nice gated road 500 that you canhike on.
Good luck and keep us posted!
