About 30 people spent Memorial Day weekend on a Bigfoot hunt in the Kiamichi Mountains in the southeastern part of the state, the Tulsa World reports. They say they have a cast of a footprint 5 inches wide and 15 inches long. Advertisement "The toes were clearly visible on the cast after it was lifted up," said D.W. Lee, director of the Mid-America Bigfoot Research Center. Bigfoot or Sasquatch is described as a large human-like creature. While sightings are most frequent along the Pacific Coast, especially in California and Washington, reports have come in from Pennsylvania, New York, Florida and many other states and several Canadian provinces. Lee described Bigfoot "vocalizations" as imitation bird calls, including whippoorwills and owls, the newspaper reported. He said one searcher was hit by a rock just after someone had spotted two large animals. Over many decades, Bigfoot hunters have failed to come up with evidence to convince non-believers.
