I try to find areas that others don't hunt. It could be a long ways from the beaten path, areas that are real hard to get too..thick, up and down ridges, right up next to a main hwy, right behind a main campsite, etc. Either hard to get to or overlooked.
Then I look for places like the above that have some sort of sanctuary close (closed area, private land not hunted much, big swamps, etc.) by and put those at the top of the list.
Another thing I look for when traveling through big public land areas on the hwy is greasy spots on the road. You see a lot of old stains there's game crossing in that area.
I use to lay in my tent at night on one big public land area and hear the semi's blowing a mile away every night...then when on stand I hear them again during prime time morning and evenings.
Where I live now I hear the horns blow right at prime times in areas I know deer are crossing roads.
