We decided to take the scenic route via the Furka pass to see more of Switzerland.  But as we exited the train tunnel, the temperature dropped to 2 degrees and all we saw was fog !  Visibility was down to about 15 metres, which made finding the road to the Gothard tunnel extremely difficult. However, a chance passing of a Tourist Information Centre in Andermatt put us back on our way.  We emerged from the tunnel 17 kilometres later to sunshine and 22 degrees.  Only in Switzerland !
