On occasion when we are out later at night investigating Bigfoot I like to do calls to initiate responses or stir the forest up a little. Sometimes it works in regards to generation a return vocalization other times it takes awhile. We were up in the wilderness alone on a very serene night no anmails just silence therefore I figured my voice could carry so its a 50/50 shot. Were were just roasting some S'mores then I did my call I did not get anything. But id have to say after my sons went to bed and the fire begin to subside a little we did hear a mix of strange vocalizations which is in the next video.
