Here in Illinois, a man driving from Cass to Tazewell County claims he spotted Bigfoot along Illinois 78 near Chandlerville. He describes the creature as having looked back at him on the shoulder of the road — an encounter that ultimately lasted seconds, but has gained traction in local news outlets and by cryptid interest groups, though legends of a Sasquatch or Bigfoot have been around for centuries. We were joined by the president of the Bigfoot Field Researchers Organization and a primatologist to discuss the legend, what it might take to prove the existence of a creature like Bigfoot, and more.
