Pristine wilderness, bear, moose, bison, deere, river fishing. Soaring snow peaked mountains that make Alps look (and actually are) tame by comparison. Gorgeous forests, cute towns as side trips/detours, glaciers literally road-side in summer that you can walk on, hot springs, charming places far apart where you can sleep/eat. Its 2-lane twisty where you can push the envelope on decent asphalt -- but at the risk of a big mammal around the next bend popping out out the woods to say hi. Its as good as nature riding gets within a 1st world country. Highest recommendation, will do it again. Goldwing is fine, as is full-dress Harley, as is an enduro.
