Why drive this stretch
Drive this stretch when you want Idaho to feel like a real next state instead of a short park-adjacent continuation. Ashton keeps the Yellowstone-side handoff readable, St. Anthony adds a more settled in-between stop, and Rexburg gives the current Idaho build its clearest larger base west of the park approach.
