MINOT AIR FORCE BASE, N.D. -- The monster truck known as Bigfoot visited here as part of the grand opening celebration of the new Tires Plus location, May 20. Bigfoot was busy in action crushing cars and giving Team Minot Airmen a morale boost, as well as a rare glimpse into what it takes to operate these trucks. (U.S. Air Force photo/Staff Sgt.
