They do leave the mountain if snow pushes them off. Lots of deer, but lots of hunters during the seasons. Easiest draw odds. NDOW manages these units for numbers not so much in the quality. But, being that many bucks, theres got to be some big ones, usually 170-180 are these types. Try units 231/161/and the 140's for a true monster. Why only unit 102? Unit 101 has about the same quality. 103 has deer but a little more spread out. The others in the 10 bracket are really hit and miss and you'll have to scout it prety hard or know someone who has and can turn you on to a nice area. Good luck.
