Idon'tchoose a location just because there are rubs or scrapes present. I choose my spots based on terian and often there does happen to be rubsand scrapes present whereI hunt.

But to answer the question...yes, I have observed bucks working both scrabes and rubs many times...not that I think it really matters. Oviously we know that bucks are rubbing and scraping whether we actuallyobserve them doing it or not.
