I often think back on how the JS, Kirk, Burnham cassettes and or CD use to call in things...wonder if predator hunting has kicked off so much that 999 callers vs 20 in a county could be the reason for how the older calling machines and software worked so well...
I remember two years ago just turning on a chip player and within seconds I hear the barks of red fox on the horizon..The bark that you have been had...wonder if so much calling do they think it was the other guy!!LOL LOL I said Barks too plural it just didn't happen once.. seemed like it was in a certain area of Cumberland county..
I read that an article one time of a well know gray fox hunter. He suggested that after awhile change to a new calling machine since they get use to the same type chatter..
