Two days before the Fourth of July a small procession of three automobiles lifted a ribbon of fine gray dust from the road that wound eastward along the edge of the Bear Paw foothills. Far back toward Dry Lake the haze was still slowly settling to earth when the last car passed through the high gate of the Flying U fence and a small slight man got out and pulled the gate shut hooked the chain around the post and into a link worn smooth with much use and climbed back beside the driver.
