This outing starts in Salmon, Idaho on Main Street, and the ride goes south on State Highway 28 parallel to the Lemhi River to Lemhi. The highway is also referred to as the Sacajawea Historic Byway, partly because of the historical fact that the Shoshone woman was born and raised in the Lemhi Valley. This passage through the high country of eastern Idaho offers interesting stories, historical legacies, and Native American rock art. There aren’t any major climbs, and the shoulder width on the highway is generally at 2 feet.
