Howl of a Tennessee Bigfoot

This was recorded in the early evening in the fall of 2007. 
I was on the back porch when I heard this abd after several repetitions I realized he was going to continue, so I went into the house, got my Bionic Ear and digital recorder, hooked them up, and came back out onto the back porch.  In the time it had taken me to do that, he moved at least a quarter mile away.  The earlier howls sounded like they were closer than 100 yards.  These sound much further away.  I tried getting closer, but had no success as the howling stopped when I had left the house.
