Where do want to start. Because they're electronic calls you can use, or mouth blown calls. Can you hunt at night in Iowa? If you can, then you're going to need some kind of lights. Your going to need to camo yourself. The most important part to camo will be your face and hands. Always hunt facing into the wind. You need to break up your outline when hunting. So find a spot where you can sit with your back to. Don't do alot of moving around, especially your hands and head. Predators will pick up your movement and and head for the next county. Go to
www.predatormasters.com and read through the forums there. A lot of your questions will be answered there. Good luck to ya.
