Ive never had much luck getting pics on rubs,, but scrapes are a different story. I get a very large portion of my pics in the fall over scrapes, if I find one early in the season, Ill keep tabs on it for a week or so, if it gets hit on multiple occasions, Ill hang a camera and keep it there until they quit coming to it, usually after rifle season. It does tell me what bucks are in the area, and when I find these large community scrapes, I get more different bucksthan oyu could imagine hitting them. Ithink its funny when some guys talk about a scrape belonging to a certain buck,, every time I put a cam on scrapes I get multiple bucks, and the little ones and big ones will all hit the same one.
