The most compelling evidence for the creature known as Bigfoot may be the increasing close encounters that are frightening witnesses in rural America. Historic stories have told of violent interactions that range from objects being thrown to frightening abductions by hairy beasts. As extraordinary as these stories sound, people continue to recount physical interactions with creatures that they cannot explain. Witnesses from Minnesota and Washington State have all had frightening run-ins with the monsters while driving; another witness in rural Indiana talks with terror of the night that he was grabbed by something very powerful out in a forest. MonsterQuest will investigate whether witness are seeing known animal or the same Bigfoot creature that has been spoken of throughout history. MonsterQuest employs polygraph examinations, DNA analysis and bite force tests to discover what monster is turning up its aggression.
