Whitetail hunters typically associate all-day sits with the rut, when a revved-up buck may run under a funnel stand at any time. But a similar approach can put you on the biggest bucks in the late season, says guide Gary Greenwalt. "By the time I can hunt, our deer are in post-rut, winter-feeding mode, and our food plots can suck in the best bucks from 5 or 6 miles away." If temps are mild, mature whitetails will feed at night. "But when it's cold—and I have years' worth of trail-cam photos to prove it—those tired, hungry, older bucks will bed tight to the feed and walk into the plot at all hours of the day," he says.
