Gun. Bullets. Knife. Rope/drag.

Don't NEED anything else. You can't learn to hunt without hunting. So get out there and hunt. Learn about the deer in your area. Develop your own style of hunting that suits your area and how you like to hunt. No sense in forcing yourself to sit stands if you really enjoy still-hunting.

Too many guys get caught up with calls, scents, clothes, etc. When they aren't successful, they think they just need to buy something else that will make the difference.

Like the old saying goes "It's the Indian, not the arrow".
