I have an open mind about things like this, and my own theories.These type of shows crack me up. Of course you are going to hear noises and even growling in the woods. Heck, I hear them at night and I'm not in the woods.
Until one comes up to me and says "Hi, I'm a Squatch", I'm going to think it's just a bear misidentified. They can stand on two legs if they want to.
