When I say I haven't heard it in 50 years perhaps I should qualify that. There was a stretch of years when I owned my own business and hunted a LOT that I averaged 50-60 days a year in the woods. I have more days in the woods than some of these people have lived and I don't hear these critters making all these exotic calls they want us to believe are every day talk all year long etc etc. It doesn't happen all that much, and certainly not all year long.
