Here in Texas since there is not much water anywhere. First find water, then start making circles around the water source until you can locate a definite trail to and from water (best time to look morning. Then try and gain an advantage point and do some watching to locate the den. Most cases the den will be within a half mile from water given enough cover. I donot do as much scouting as I need to, for the most part I just locate water on ranches and figure the best way to approach and try and get to a vantage point and call, works pretty well.
Bob I hunt some this time of year, as ranchers donot care whats going on they just want them dead.
