Road quality is good on US-395 and I-84, but OR-140 and US-395 north of Lakeview have intermittent shoulder drop-offs and wildlife (antelope, deer). Winter snow can close passes; always carry chains. Summer brings afternoon thunderstorms in the high desert.

• Fatigue management: Plan to stop every 2 hours. Rest areas at Diamond Valley (NV), Lakeview (OR), and Barnhart (OR) have shade and tables.
• Hidden spots: The town of Summer Lake, OR (off OR-31) has a hot springs oasis. The tiny community of Wapinitia (near Maupin) offers a rustic general store.
