Great topic. I've been hunting fall turkeys for many years now and enjoy it fully as much as hunting in the spring. I get to see huge flocks of birds, watch their behavior and hear all the vocalizations. I've been within just a few feet of flocks of 100 or more many times. If you want to learn to call like a hen, there's no better way to do that than to be a few feet from a large flock and just listen as "mama" calls her brood together.
It's also amazing to "bust up" a flock, wait just a few minutes and then call them back. To see and hear turkeys coming from several directions, calling loudly, is a thrilling experience.
The most important factor, in my opinion, to fall hunting, is to hunt where the turkeys are. I know how simplistic that sounds but it's absolutely true. They are in flocks. They stay in flocks and if you don't locate where the flocks are, you're just out of luck.
If you can watch the fields during the summer and early fall when crops are out, you'll see them. If there's a water source and they aren't disturbed too much, they'll probably be around somewhere when the season come.
I do scout in the fall but I don't just get in the area and walk around. I go and sit, even sit in my vehicle, just watch and listen.
The most important call in the fall is the kee kee. It's about all that I use or have need to use. I like mouth calls and again, that's all I use in the fall. I can do a better kee kee with one than anything else and I don't have to move to use it.
I like to go out the evening before the first day of the season (check your laws to make sure this is legal) and locate a flock. I want to know where they are on the first morning. Get in early, "bust them up" by yelling, hitting trees with sticks or even shooting in the air. Then find a comfortable spot close by, wait a few minutes and start you kee kee. If your "bust" was good, scattering them in several directions, they will return and then the fun begins.
Lastly, the fall is a great time for a social hunt. The more hunters that are with you the better. You can scatter out on a ridge after a bust and call. I've been on hunts with as many as 6-8 of us in a line waiting for the birds. It's a great time to take young folks as well. Just get them in camo, let them sit beside you and they won't get bored. The action can be fast and furious.
I truly believe if you ever try a fall hunt and "hunt where the turkeys are" you'll be hooked on it forever.
