HONESTLY, DURING THE 4 HOURS WE WERE THERE, THE ONLY 2 CHASES WERE DEER. THE DOGS CAUGHT ONE IN THE BACK OF THE PEN, THE OTHER ONE JUMPED THE FENCE. I DID SEE ONE COYOTE CROSS THE PATH AT THE LIGHT POLE BY THE OLD FEILD, NOT ONE DOG EVER HIT THE TRACK (NOT EVEN MINE, AND I HAD ONE DOG THAT CAME ACROSS IT RATHER QUICK AFTER THE YOTE CROSSED). I'VE RAN THE PEN BEFORE, SOMETIMES THE DOGS RUN HARD, SOMETIMES THEY JUST CAN'T SMELL. THE PEN HAS ALWAYS BEEN THAT WAY, EVEN BEFORE EDDIE GOT IT.
