Topo maps in general, along with aerial photo surveys, are useful tools when it comes to new territory. They won’t show problematic features, such as hog-wire fences sure to cause a gobbler to hang up or old logging yards that have become prime dusting spots. But they will provide a feel for the lay of the land: where to call and set up, likely feeding areas, and more. Add to that studious on-the-ground study of sign—strut marks, tracks, droppings, scratchings, dusting bowls, and roosts—and you’ll be using your precious hours afield to maximum advantage. Sound woodcraft, especially knowing your prey and reading sign, trumps everything else, including calling ability, when it comes to filling tags.
