Deer hunters spend so much time trying to pattern deer that we forget that we also can be "patterned." After all, most of us hunt the same days and the same hours, so it isn't difficult for deer to figure us out.
While we would never recommend giving up hunting the traditional moving times for deer -- early morning and late evening -- it's important to keep in mind that deer will move at other times of the day. Sometimes hunting through lunch, or getting in your stand earlier than usual for an evening hunt can do the trick.
In addition to staying on stand through the lunch hours, another thing you can try is hunting through the week. Sometimes deer let their guards down when there are fewer hunters in the woods. Whether it's the slamming truck doors in the pre-dawn or some other "sixth sense," whitetails tend to know when hunters are in the woods. Give them a surprise and try to make it out there a few days that you normally wouldn't hunt.
