We cycled for several hundred miles along the Rocky Mountain Trench, a deep, nearly straight, 1,000-mile rift between two of the region’s major mountain ranges. Along the way we discovered the headwaters of the Columbia River, disrupted a secret plot by a small band of wild turkeys, and eventually crossed the border back into the United States. With some deft planning, we also managed to piece together enough dentist appointments (in multiple cities) to finally take care of a nagging toothache. The mixture of gorgeous scenery and logistical complications ensured that each day was both hectic and an adventure on the way to Libby, Montana.
