BEDS: Mark every bed you find on a GPS or map. Spring bedding areas may not be used in fall; on the other hand, they may. So be sure to add them to your inventory.
RUBS:** Rub lines reveal specific routes taken by bucks during the hunting season. As long as the snow isn't deep, last fall's hashed trees will be plain to see. Follow every rub line you can decipher, making note of ambush points. Watch for clusters of rubs, too, which indicate an area that gets a lot of use.
