Rubs ALWAYS tell you one thing for sure, a buck has visited the area. From my experiences, this is not an isolated event, the buck that made the rub will revisit the area at some point.

If I were you I would do some investigating to see if you can locate a rub line. If you locate a rub line, you are in the right spot. This is an area where the buck in regularly traveling and feels safe.

If I were you I would leave the stand there, and carefully hunt this buck. If he is as big as you say, he will not tolerate any human intrusion.

Be very careful with scent control. Good luck.

Hunt the thickets
