On public lands I hunt-which is the majority of my hunting-I rule an area out the same way I rule it in. After scouting, I make determinations on the better areas. I will do all day sits to see if the location meets scouting expectations. If nothing comes, I may hunt it the following day or skip a day or two, then come back for another all day sit. The reason for this is that a deer that doesn't show on the first day may routinely return to their pattern on your next ADS. If I don't see a deer on the second sit, I wait a week or so and come back for a third all day sit. The point is, if you've scouted and read sign properly or have seen deer in the area prior, then chances are good you will see the animal during season-doe population depending. If the animal doesn't come after the 3rd all day sit, then I consider the area as non or low probability and spend time elsewhere. The point being, let the area tell you if it's productive or not. Sitting an area for a small portion of a day and constantly moving to other areas, is not a recipe for success from my experience.
