Expect bucks to come in from the downwind side. On the best days, I've rattled in a dozen different bucks and then on the very next day, I've had nothing respond. When the whitetail rut hits its peak, deer movement no longer is limited to very early and very late in the day. All three bucks had their tongues hanging out, indicating that the chase had been going on for some time. Hunting all day is a good tactic during the peak days of the rut.
Bucks cover lots of ground searching for receptive does.
So hunting from an elevated vantage point with strong binoculars and spotting scopes, where you can cover lots of country, is a good idea. This allows you to evaluate more terrain from one location than you possibly could see from a ground blind. A tower blind, hilltop or even the high rack in the bed of a pickup all are good spots to give you a commanding view of the surrounding landscape. Another important element for a good hunting strategy during the peak of the rut is hunting in areas with lots of does. A combination of hunting all day, hunting from high vantage points, and hunting in areas with lots of does all will increase your chances of finding a buck on the move during the peak of the rut.
