i have always known turkey to gobble mainly in the spring and early summer then you usually dont hear much out of them the rest of the year. however last year during PA's rifle season in early december i was 100 yards away from 3 gobblers in a tree that just would not shut up. they gobbled probably 50 times and it was about 25 degrees. i was mad because all the deer hunters in the area heard them and will now be invading my turkey hunting area this spring. [:@] in the spring tho, i noticed when its windy they only gobble once or twice if at all. on calm days rain or shine they usually always gobble for me.
