IMO trying to scout sign during the summer is extremely tough. Foilage is grown up making it difficult to decifer sign, and like the good doctor said, patterns change between summer food to bed and fall pre-rut and rut. I would personally use some scouting cameras to get an idea of the type of deer in the area, perhaps try to glass some feed fields if available, and that's about it for in-the-field scouting. Then I would look at a topo map for potential travel corridors and hang/hunt when the season starts. I would start on the outskirts and areas I thought were good potential bed to food routes, then move in on movement as I saw it unfold during my hunts.

But of course I don't have a wall fall of monster bucks so my opinion may be null and void around here.
