IMO there are two ways to look at this- one: I would recommend that you DO NOT diminish your productive one by one square mile hunting area in any way. Set up your buck bedding areas, and I know you've had success in your downwind edge doe bedding areas during the rut as well. WHEN you are satisfied you are completely ready to roll for the upcoming season, THEN branch out to your other areas. The new areas will help you reduce your impact on the deer you are hunting, and maybe you will strike gold. Why do I recommend this? I know a LOT of guys who spread themselves too thin and didn't prepare the areas they already knew so well the way they should have. They had some ROUGH deer seasons on public land because of it. Get your work done, then expand.

two: going in a different direction here- there are hunters (Dan and Troy come to mind) than can look at aerials and topos and quickly go to new areas and be successful. They recognize things on the ground while spot checking the areas that take years of practice and skill as well- subtle mature buck sign/bedding areas/transition lines/islands etc. This is an exciting way to hunt, and if you become good at it ... nuff said. If you aren't confident of this, SEE PARAGRAPH ONE ABOVE.

My final overall recommendation- get your work done on the spots you already have a lot of experience with. Then expand your opportunities with the knowledge you already have.
