Big truck gets stuck in Zion tunnel; driver blames GPS

back in the forth's a semi got stuck at the umatilla army depot under the railroad track over pass. they tried every thing to get it out and couldn't. the semi was loaded with bombs for the war effort and a little kid told them he knew how to get it out and they ignored him until they finally gave up and said OK how do we get it out. he told them let air out of the tires so the truck in lowered. it worked.
