Migration???? What the ..........
I'm sorry dude. I may not be the person to ask and I may be totally in the dark since I've only been hunting there since I was 4 but anyone can correct me if I'm wrong. I am very curious as to where these deer are migrating from?
If you plan on hunting the migration you might as well stay home cuz there won't be any migrating deer to hunt.
Wait just one darn second, those deer do migrate. When the snow hits they migrate from the south side of the hill all the way around that darn thang to the north side of the hill. Yep they migrate all of a few hundred yards! I have pictures of bucks in 3 feet deep snow in the middle of january in the middle of hay canyon. Why are they there you ask? because there are so many pockets that don't have snow that they have no reason to migrate. Just go walk around up there some time. There's always places to browse.
If you do want a fun hunt do this. Have someone drive your truck, get in the back in a chair with an arrow knocked and drive back and forth on the highway between pinon and weed and you will have tons of shots on big bucks and its a blast. If your stalk is ruined by deer being jumpy because of running engines then no worries matey! Drive up the road and find one a little more road hunting friendly. You will absolutely get a buck that way cuz there's tons of those darned migrating deer simply standing on the road. Seriously though, I'm not kidding.
