So many, it is hard to say best. Some highlights:
First turkey(s) I ever killed- fall hunt in NY. I had been struggling to figure it all out, a farmer gave me a tip on where birds had been roosting. I set up under a likely tree that turned out to have 30+ birds roosted in it. They flew down directly below, I found myself pinned down with 30 birds on the ground around me. After an eternity I was able to get my gun up and fire a shot, wound up rolling 2 birds.
First fall bird I ever shot with my turkey dog Maizy (PA).
Limited out spring season opening day in Georgia last year, 3 longbeards in 1 afternoon, 1 had 4 beards.
Spotted a bird in an open field in GA spring season, 300+ yards away, about 10 years ago. Threw a Hail-Mary gobble at him and waved a tail fan, he came running full trot, seemed as if I had all the time in the world to get set up. He rode home in the truck that day.
