Zombietom69 on YouTube had this compilation up. It intrigued me. I've been fascinated with Bigfoot footprints, but the sounds recorded that people have taken to be BF are sometimes explainable and sometimes totally chilling.
Here is a supposed Bigfoot call entitled "Old Man" (warning, do not drink anything while listening--it will spew out your nose!) It cracked me up so much, I'd listen to it over and over again on my computer while doing things and my son would come in and roll his eyes in exasperation. His mom is such a dork! Seriously, if I were the type to carry a cell phone, this would be my ringtone.
I'm curious. Did any of those calls ring "true" to you. I think there is something about our animal side that recognizes other animals, especially "relatives."
