Thanks for the suggestions. I was considering going from one group of hardwoods to another to see which ones have the most sign/trails. A buddy of mine used to hunt a somewhat similar area to this and he said there were two mature trees surrounded by this type of terrain and it seemed every trail in the area came by those two trees for some reason. When I go back to scout again, would you guys think the most likely hot spots would be the strips of hardwoods on the hilltops or the valleys?

Also, if I find some good trail intersections/sign on the hillsides, what do you think about setting up a tripod next to or over one of the nearby small trees?
