I'm a real stumble-bum in the woods sometimes and am perfectly capable of finding every single loud snapping twig on the ground. So as long as I know the woods I'm going to be hunting fairly well, I like to just listen from the road at the magic 1/2 hour before sun up to get a general idea where gobbles are coming from. If I can time it right, I also will do the same when theres an approaching t-storm, that will many times get them fired up also (and give away their location)
