Welcome to the board! My opinion is that you are trying to hard. There is a lot of DNR ground, and private forest land in 448 that holds animals and doesn't cost anything for you to walk into. Most of it is actively logged which is ideal habitat for blacktail. High elevation has its pros (i'm assuming you have been looking at high elevation since you mentioned trails and impassable terrain...?) like getting away from people, better class of deer in general, etc... I would start with a DNR maps, National Forest maps, and also find where private forest land owners other than Weyerhauser are, and start there. Find some good 2-5 year old clear cuts and start scouting the edges looking for sign, it should be there.
