I think I'll end up averaging 60-80+ miles a day, allowing me to hit the West coast in probably 60 or so days.
My biggest concern is crossing the Rockies in September. Do people think this is a terrible idea or worth the adventure? Any experiences about crossing the Rockies later in the fall would be super helpful!
That depends. As the month of September progresses, the chances of snow is greater. The chances of a paralyzing snow storm is next to zero. Even into October the amount of snow that might fall is rather low.
This article gives some feeling to what to expect in Yellowstone.
Here’s the same data for Breckenridge. That is a shorter term average than previously presented and reflects current conditions better. Bottom line: you’ll experience cold temperatures (32°F or lower) but probably not snow.
On a positive note, afternoon thunderstorm activity is significantly reduced in September. They can still happen (just like it can still snow) but they are less intense and less prevalent.
