I really got into topo map scouting this off-season. I suppose it will take me years of hard scouting/comparison to topo maps to be proficient. But I can tell you one thing....almost all of the big rubs I found out in the middle of the woods were made on the edges of saddles....and all the massive scrapes were placed directly in the middle of those saddles. I had never seen buck sign like this until I went out deep in the woods specifically looking for saddles based on the topo maps I looked over. I know have 4 saddles spaced out over a mile in the woods that I am REALLY looking forward to hunting come October 30th-November 20th....
