Beautiful, green, hilly, empty (nobody home) -- the road from Arco, ID to Helena, MT was another spectacularly scenic road. There were many farms, and then we went up into the mountains. Travelling north on I15, we noticed that exit zero was for Monida (name made up from Montana and Idaho). The town is right on the state line.
Passing beautiful lakes, the road went through mountains of brown, green, and red. 
We crossed a mountain pass at 6000 feet and noticed a warning sign and a pullout for putting on chains (hopefully only in winter).
Another pullout is found after the pass, for taking your chains off. We didn't actually see any snow here, but we did encounter some rain.For more pictures, click Road to Montana
