Wow, those first two were really interesting with the historical narration. The land reminded me of a ride I took last summer in the Sawtooth Mountains area of Idaho, near Boise. Hwy-20 and -21, went through Idaho City and Stanley, later Sun Valley, 500 miles total. it was incredible.
I'll hope to check out Lolo Pass soon. Glacier Park and Yellowstone would be great too. Almost took Sidecar to Yellowstone two years ago, but got cancelled at the last minute...
