I watched a nice 8 make a scrape once. He was dogging a doe, and she stopped to feed under a white oak. He started working a licking branch, quite vigorously actually, and made a scraped under it where he promptly peed in. In just watching that, it SEEMED to me as if it were a way to off load some aggression and frustration.

I also saw a buck make a rub once. Little spiker worked over 2 saplings pretty good. When I exited my stand that day, I went over to look at them. Yeah, he actually tore them up pretty good.
