The places where there is plenty of sign,but you are not seeing activity in the morning or evenings.So there are two other times they could be there..midday or 3 am.Clearcuts,powerlines,gas lines,foodplots,railroad tracks,curves of roads..Places they think they can go in midday,but know better than to go in the morning or evening when they know hunters will be out.Later on in the season,we sleep in more often.I had shot a 6pt the week before christmas at 11:30 am.Christmas eve my friend shot his first deer a 3pt at 11:45am.Both areas were High pressured public land,and we waved to people leaving as we came in both times.They have to move sometime.They will sometimes bed close to the roads,and listen for vehicles to leave.Down here I have found out that in the late season the deer generally bed down around 1-2 hours before light.Herein the late season daylight is around 7am.Then they get up after about 6-8 hours of bedding to water,stretch,move to some sunlight to keep warm.That's why I like grassy clearcuts.The deer will move into them after the sun has melted the frost,and then they will lay in direct sunlight.Then after an hour or so,if they feel like going back to the woods they will.If not they stay alert for hunters,and slip out when they detect some.Then usually they start moving around an hour after dark.Sometimes you can catch deer moving at daylight or at dusk,but you guys know how hard that is in thick terrain after thanksgiving.Hope that helps.This is just my observation with high pressured southern deer.
