Those guys laid the foundation for me when I was younger that imo is why I've been successful.
Learn the woods you hunt, every tree, every opening, every hill and dip. You should know it so well that before you even make a set up you envision it down to the tree you are gonna be at before you even make a move.
Study turkeys and their behavior. Why are they doing what they are doing. Where do they like to go after fly down and why. Where do they stage in the heat of the day and why. Where do they stage before fly up and why. If it's raining where will they be. If it rained over night does that change where they go in the morning. If it's windy do they like certain places. Some of that can't be answered all the times because turkeys will be turkeys, the point being is educate yourself on WHERE and WHY. If you make a mistake, great, learn from it and what could you have done instead.
Between those 2 alone you can kill turkeys anywhere with enough time and effort.
Calling was always their lowest priority, but their main leases was when to call and when not to call.
