DEER RIVER, Minn. -- Some say footprints found in northern Minnesota belong to the legendary Bigfoot. The prints were found by a Cass County grater operator near Deer River, Minn. When Bigfoot believer Bob Olson heard about the footprints from his granddaughter, he went to see for himself. He made casts of two of the 15-inch prints, which make the 6-foot-5-inch tall man's size-14 feet look small.
