I spent 3 hours today working a big tom that would not budge for a call. I tried it all, diaphram, glass call, even gobbled at him, nothing. Just sat there and gobbled his fool head off. I finally belly crawled to within 80 yards when i saw him just a struttin and gobblin. Ease my back up to a tree, get my gun up and scratch out a yelp on my glass call. Deer stands up between me and him and blows about 10 times. Game over. Bout broke my heart. Lol. Oh well, least i got to play the game...
