Stick to the German-speaking cantons, but don't tell them they speak a dialect.
Trust me on this.
“However weak the individual white man, his ancestors produced the greatness of Europe; however strong the individual black, his ancestors never lifted themselves from the darkness of Africa.” -- Carlton Putnam
I've been to Switzerland a few times when I was a child. Very beautiful Country. RIch with spirit. Nice people too. They have these long tunnels that go through the mountains, the Swiss Alps that is, of course. They have tank traps in them to stop any tanks coming through. Large blocks that close up the tunnel. Thing that I remember other than the landscape is the amazing old buildings. Farmhouses and such.
"If I were going to construct a God I would furnish him with some ways and qualities and characteristics which the Present One lacks... He would spend some of His eternities in trying to forgive Himself for making man unhappy when He could have made him happy with the same effort and He would spend the rest of them in studying astronomy." ~ Mark Twain
