it's not neccesary to have but a blind is how 99% of hunters get there bird. place your decoys at 25 and 15 yards. ideally you want tom to come face to face with your decoys. another tactic you can do is position your hen at 10 yards and a jake only 2-5 yards away from your blind. attatch some fishing string to the jake so you can make him move. If you don't have a blindtry hiding behind a fallen tree or just pray he turns around while fanned out so you can draw your bow on him, risky but it';; work
