Local winter tips
- Local climate varies a lot by elevation — check conditions for your specific route, not just the state average.
- Mountain passes drain range on the way up; plan for the climb rather than the round-trip average.
- Winter tires are strongly recommended given the mix of snow, ice, and mountain grades.
