Untitled Sighting

Well, my younger brother saw it when he was around 8-9 years old, in the late '70's. Our home was somewhat isolated and had  woods all around it.  We  played in the woods a lot.  He told me that once he saw "Chewbacca" standing in the woods watching him.  Over the years he heard weird noises coming from the woods when he was walking down the road, like screams and grunts that were almost like words.  He describes them as "chanting"  or sing song. Also, while by myself in a field beside our house, I heard a very frightening noise coming from the woods at the edge of the field; like growling and snarling  coming from somewhere behind the trees.  I saw nothing, but the best I can tell you a very large animal made those noises. Since the noises were loud I could tell the direction they were coming from easily and it was way above my head from the tops of the trees.  I never heard any animal before or since that made a noise like that. Being around 10 or 11 years old, I didn't hang around to check it out, but later I told my brother and he related to me about the time he saw "Chewbacca".  Then one of us wondered out loud, "Was it Bigfoot?"  To this day, we don't know.
