With Your Buckpole.net Guide: Jon Book

It's never too early to start looking for rubs. You know where the old ones were, but start looking. Some bucks start early in testing the antlers. Big or small, watch for the creamy white collar of bark rubbed off or small bushes with a lot of busted up branches.
The real rut season is only a few weeks away and the bucks will be splitting up to go their separate ways.
Rubs will generally be made in or along the bucks path to and from food, water and cover. Look for all kinds of signs relating to your bucks movement.
Be safe and good luck.
