If someone asks Paddy Murphy what the best way from Bellinzona to Glarus would be, he will answer: Nufenen - Grimsel - Susten - Klausen. This episode shows two of those mountain roads. Grimsel Pass is like a motorway over the mountain, when you start in Gletsch, wide road, some serpentines and long, straight tracks.
The similarity between the San Bernardino and St. Gotthard Passes is that both mountains can be circumvented using major traffic tunnels. But nobody in his right mind would prefer a tunnel over a mountain pass road! Some say there is an alien base hidden in plain sight on the summit of San Bernardino, but who believes in ghost stories these days anyway.
