FRANCE
Once arrived in Karlsruhe, very likely I will pass on the French side of the Rhein
SWITZERLAND
Nord-Süd-Route 3, Basel-Chiasso taking the old track of the Gotthard
ITALY
More or less I should know how to get home …

After hundreds of trips in Germany, most of which related to my work, it’s the very first time that I have the opportunity to cross the whole Country from North to South.
It will be a big pleasure, and honour, to see, visit and know it from this totally special and surely very challenging new perspective.
Thanks to everybody for your suggestions.
