Just keep after them, don't get discouraged, don't overthink your calling. Turkeys are fun to hunt. Starting out my biggest hurdle was not second guessing myself or my calling. When you first start out its easy to get discouraged if you get in a group of older birds. They seem to sit and strut out of range then turn and leave and naturally the first thing that comes to your mind is what did I do wrong? Don't worry about it, get on another group of birds or change locations the next morning. Go out hunting as often as you can no matter what time of day. If you put your time in and hunt where there are turkeys, you shouldn't have a problem getting a shot opportunity. I think the most important thing to my set up is roosting the birds the night before. Get on a ridge before dark and glass till you find them, that will give you a great starting point for the next mornings hunt. Just remember not to set up too close and the earlier you get set up the better. Good luck!
