I learned a few things:
1) I don't have a 50yd gun - I have a 70yd cannon.
2) Expect the unexpected when taking new turkey hunters.
3) If you're not seeing birds in your honey hole, then scout hard and move to hotter properties.
4) Strange and unexpected changes in weather can drastically alter bird movement for an entire season.
5) Well-designed strategic hunting plans are great - but in the end, trust your gut at the moment of reckoning because it's almost always better than your predesigned plans.
I have advanced degrees in animal science and 25 years of experience, but this past season reminded me of a very hard lesson - turkeys do what turkeys want to do, when they want to do it, and you can't always understand nor explain it...
