They would follow Route 82 south over the Columbia River until it hit Route 84. (According to the map, the meeting of the two highways wasn’t more than a klick from the Tir Tairngire border. That was closer than either Sly or Falcon really wanted to get, but any other route would have added hours to the journey.) Then it was southeast on 84—but bypassing Boise if possible—and on to the Sioux border at Pocatello. From there, the only available major road would dip down into the Ute Nation, so they had to take to the "blue highways"—the secondary roads—until they could pick up Highway 80 at Rock Spurs. From there it would be a straight shot roughly east, through Laramie, until they hit Cheyenne.
