Shotgun, choke and shell combination that will pattern at least 100 pellets in a 10" circle @ 40 yards to point of aim. Comfortable boots, comfortable seat pad, a way to pack water, calls, a snack, clothing layers, compass and topo map, and a turkey back to the truck. I like a vest for that. If you elk hunt and use a diaphragm call then you can easily use a diaphragm turkey call. Get a few in different pitch/tones. Maybe a friction call like a pot/peg or box call. A locator call like an owl hooter, coyote howler, ect. Patience... lots of patience.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
