Haven't done much late season hunting lately, but when I did, it wasn't unusual to sit dark to dark. Going to have to hunt late season this year if I want to eat venison. Pretty sure I can't take the cold for all day sits like I used to so it will be a couple of hours in the morning and a couple in the evening, with maybe still hunting and/or scouting mid-day.
Do some scouting first. Deer usually herd up a bit, particularly the does, after gun hunting seasons over and they make trails to/from bedding/feeding areas. Find some of those and set up accordingly. I generally try to get closer to bedding areas in the morning, hoping to catch them before they come back to bed, and nearer feeding areas in the evening. Regardless, In my neck of the woods,they often move the first or last half-hour of the day and not much in between unless spooked by small game hunters, dogs, etc. They move a lot at night, of course. Good luck.
