Goals are good. Hmm, you got me thinking about doing that here in WI. I've hunted all the WI units but not all the counties inside the units. My problem would be the number of years I may or may not have left.
Years ago I set a goal of hunting something in all 50 states, doesn't matter the species or whether or not I kill something; just to hunt. I have 11 left. This has been the best goal I ever set for myself.
Perhaps on your goal you might want to modify it a bit. Just hunt turkeys in each county rather than killing one in each. As a one who has hunted for more than half a century I've learned there is so much more to a hunt than just the kill. Don't misunderstand, I still like to kill turkeys or whatever I'm after, but some of my best most memorable hunts did not result in a kill. So why not count those as a hunts to your goal?
It's all good, enjoy your hunts and stay focused to achieve them.
If you agree with me call it fact; if you disagree - call it my opinion.
After all - we are talking turkey.
