I started a deer hunting journal on the farm I hunt (and now own) in 1988. It includes:
Date, times hunted, clouds vs sun, wind speed and direction, air temp, stand location, is the corn/soybeans up or harvested, snow or not, who hunted with me and how they did and a place for a narative.
I'm not sure how much it improved my hunting, but I can go back 20 years and read the narative and it is like I was there again. All my deerhunting memories are there...my first bow kill, first buck, my daughter's first deer and on and on.
Sometimes when I miss a nice deer it is hard to sit down and write it up, but I make myself do it, including my emotions and feelings.
I plan to hand it down to my daughter when I am gone, so she will never forgot what deer hunting has meant to me.
Forgot to mention that the farm is in northern Trumbull county near Mosquito Reservior, northeast Ohio
