Hey, SouthArk...I'm seeing a lot of rubs at my place in Conway County. They started out slow....there were very few in mid- Sept....but when I went back last weekend there were lots of fresh ones. May be that you're just lagging behind a bit. Some folks dont think the temperatures have much to do with stimulating rubbing and scraping activity, but I'm not so sure about that based on my own experiences.
Good luck!
