I wish I could make better use of maps and aerial photos when beginning the scouting process. Unfortunately, I need to spend time on the ground. I can see trails, empty beds, creek crossings, etc. and get a better than fair idea of animal movement. One thing that plays into useful scouting is being familiar with what's on the surrounding areas. I am often amazed at what guys glean from these photo maps and the hero pictures showing up later in the season based on this scouting. I guess a lot also depends on understanding topo maps. When I hunted public land, there were relatively few areas that had food plots and crop field that made a major difference in the productivity of the National Forest land I was on. Then, I looked for thick places that were not close to the road. Isolation is a factor in the consideration of cover.
