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.

Corridor read
This segment is meant to keep the Route 20 chain readable rather than turn every stop into an equal destination. Use the map and the compact companion rows to decide where the real linger time belongs, which support towns are mostly practical, and when the next live segment is the better continuation.
Treat the strongest anchor here as the place that carries the planning weight, keep the support stops proportional, and use nearby add-ons only when they genuinely strengthen the drive instead of distracting from it.
