i gotcha ya. your talking about rubs or in area where you have quite a few in a row rub lines. a fresh rub would look like someone took a knife to it that day and scrubed bark off of it. and old rub would look like its been awhile or even a year since someone took a knife to it. check out these 2 photos in the hunting tips section. its under deer rubs. the 2nd one is what i would call a pretty new rub. the 3rd one an old rub.
here i will just put them here for you
