I have taken several large bucks off of rub lines. If you find a fresh rubline and follow it till it starts to enter a thicket that is probably his bedding area and set up. Most stageing areas are just littered with clusters of rubs, and sometimes have several rublines leaveing them. Seting up right in the stageing area is very produtive. One thing to keep in mind is that bucks will stop and rub trees all over the place, a few rubs in an apparent line do not make a rubline. Most of the rublines i hunt have lots of rubs along the same trails and are very distinct. The bucks come out of the bedding area very slowly like they really want to go somewhere but also want to be caustius, and seem to rub one tree after another as they wait for darkness.
