CD had declared it was a family camping visit that brought him to Idaho, which was thought to be one of his motivations that "he had to come to Rexburg". Does anyone have any idea where that was in Idaho..
Island Park. Take highway 20 north from Rexburg 30-something miles and you're in the Island Park area. It stretches for about 20 miles before the road starts climbing over the mountain to West Yellowstone, MT.
