Never personally hunted out there but I've hauled enough cattle out of there to notice some things ........ From Dickinson west to the Montana border I've seen some really nice deer. It's rocky and rugged anywhere in and around Roosevelt park on the west edge of the state and over the years I've seen a lot of nice deer pulled out of that area. I spent some years hauling for a ranch near Glen Ulin also , more open broken up country but I've seen some really really nice bucks in that area too. I guess if it were me I'd be looking hard in both areas. Some of the better deer out there are completely out in the middle of no mans land where you'd least expect them , good luck !
