Dude,

Im feeling ya on this one. I hunt on land that has about 40 head on it. I hate those cows man. I was out there scouting and thought I had found the mother of all deer trails only to look up and see a cow taking a dump in the middle of the trail. There really is no way to tell except that cows usually wont climb the taller hills and of course the tracks. And they will probably stay to the edges of the thick stuff so if you see any trails running through the thickets thats probably a deer trail. However when I hunted in MO during the opener this year. I saw trails up there that looked like cattle trails but they werent. Those deer had worn them to about 8 inches deep. Hard to miss those. Hope I helped
