scouting is a year round ordeal. My favorite time to scout is Post Rut and late season early to mid winter...
Ialways chart and recall old Rub lines and scrape lines, bedding areas, feeding areas as seasons change. acorn and differant natural forage crops will peak at differant times, also dependant on weather dry/wet season.
also when Hunting I try to pay close attention to all deer I am seeing on stand, where they came from where they head too. and always try to analize why that is. where did they come from and where are they going and why. They seldom wander without purpose.
another great scouting tool is the game cameras. they allow you a sneak peak at the Bucks in your area, and will give you insight as to the quality of deer your areas holding.
