When it's cold and snowy here, I hunt south facing slopes with some blow down on them. They're usually bedded out of the wind and in the sun.
Getting close is obviously the issue, so is the snow good for sneaking on or is it better to set up before light and intercept them coming from eating?
These places may not be year round bedding areas, because they're more open to let the sun in. Also picking the blow down they'll be bedded behind is "interesting." Find the trail(s) they come in on is helpful.
Where I hunt is more big woodsish or the food sources have changed. Brouse is harder to pinpoint in a woods situation, so I'm more inclined to seek out the bedding/chewing the cud spots after the snow hits.
I don't bait as the few times I tried it,I found I was feeding the night shift.
