My son-in-law's father saw one se of Mankato, MN, about 15-20 yrs ago. He was going out hunting driving on a gravel road, looked over at the corn field next to the road and saw one standing up, head above the mature corn, it ducked down when they made eye contact. I doubt he would make up a story like that, he couldn't say anything being an employee of the IRS. Probably wouldn't be collecting a handsome pension if he had.
