I have consulted a map. A road atlas of Europe to be exact. An atlas so old (circa 1983) that the M25 is indicated as "under construction".
Confusion arises as to whether you are in Switzerland or Leichtenstein,
Aannyway, yes I have been to Sargans, probably while doing a Train based jolliday based in Davos. This tour would also have included Landquart, Vaduz and Zizzers, amongst multitudinous other lines and stations, It was a holiday for hardened Rail Fans.
I am sure it was Sargans where I purchased two Romansch phrase books. One French/Romansch and one German/Romansch. I gave one away to a friend who is also very interested in languages.
