Sometimes, late-rut whitetails will concentrate in pockets with great food and cover and reduced hunting pressure, and their sign will be evident. If you can find such a spot, hunt it right at daybreak (either from a stand or by still-hunting) and stay there throughout the day. But if no sign is showing, spend the morning covering ground to get into deer again. In farm country, drive around at daybreak, glassing for deer returning from feed to bed, or even a buck-and-doe pair in an oddball locale. In big-woods country, put on your still-hunting boots and start covering ground to get on the freshest sign. With any luck, you'll have snow to make your search easier. When you find fresh rubs, a recently worked scrape, or better yet the deer themselves, hunt that spot until dusk, working calls and rattling.
