I witnessed multiple wood knocks throughout the valley of Macedonia State Park (in Kent) 8 years ago. Was it Bigfoot, I have no idea. I will say this, the knocks sounded like some sort of communication and were heard at different directional points in the higher elevated areas for close to 30 minutes. SRP is a well known location for hiking, horse back riding and cycling along the Shepaug River in Washington Depot Ct.
