Found this one the other day. The pic doesn't do it justice but that backpack is pretty big. One of the biggest rubs I've ever found. The next pic is pretty cool. Shows several trees getting whacked year after year.
Cool rub jay. I found one of the largest rubs I have ever seen this past Tuesday while scouting, I wish I had a camera. It was in a remote spot that I will likely only hunt with a perfect wind during the first three weeks of October. Bring it!
