How is the drive on US 12 from Yakima to Morton? Are there steep grades and sharp curves? Not sure if should come from Yamika or from I 5. We would be traveling from Spokane. Thanks,
That's just t nice two lane back road that doesn't get a ton of traffic. It's in good shape and doesn't do any super sharp turns. IIRC there are some hills but nothing bad really. You'll be fine.
