I dont hunt rubs or scrapes, those are just tale sighns that bucks are in the area. Set up in some cover down of the scrapes, or use funnels. I have dozens of rubs and i have seen bucks rub right under my stand and never return. I have found rubs with scrapes in front of them and they have never been used again either. Bucks are very unpredictable, just get a good set up with a good dominate wind in your favor and hope for the best. You cant kill one sitting on the couch!

HEre is a buck bedded down right by a cedar tree with a rub on it. Can you see the deer?
