That's complete BS. Yeah a difference in a jake and an adult most of the time but no difference in a 6 year old and a 2 year old. Gobbling frequency has nothing to do with age, I've killed several long spurred gobblers that gobbled their heads off. As far as your spotting scope comment, you're full of it. 1 and 3/8 before you've completed your season, hahahahahaha BS. I've forgot more about turkey then you'll ever know and you can be retired as many years as you want but that doesn't make this true. Enough Said.
