Late season geese LOVE corn. From talking to moosie, getting on land can be kind of a pain in the ass, but late season hunting is some of the best of the year. However, land can be freed up that late cuz alot of the weekend warriors hang up the shotgun after most of the water has frozen up.
Late season geese will also only feed once a day usually if it's cold out, and may not feed at all on really cold days. So scouting the mid-morning to afternoon is the best time to find geese flying back and forth from water to fields. Geese this time of year also seem to get dumber and dumber the colder it gets, and may set you up for a great shoot.
