Great trip and great shots. I have been to many of the places you visited. There are some great pics of Lindau on the Bodensee on page 1. One of my fav spots in Germany.
Next time you go to Italy send me a PM. Milan & Genoa are both forgettable but close to great spots. Next time skip Milan & go to Lake Orta, Lake Como Lake Maggiore or Lugano. Skip Genoa and see Portofino, Santa Margherita Ligure & Cinque Terre.
The sign above the big flower pot/ trash can looking thing says,
Io sono un fragolina di bosco...
I am a little strawberry plant
Non c'è un cestino per spazzatura
Not a waste basket for trash
Hence the little plant inside.
