I've made a list of all the places we visited: 32 places in approximately six weeks. And I've started to sort the photos. Here's the list sorted by country.
Frankfurt, Kuppingen, Herrenberg, Tubingen, Stuttgart, Rutesheim, Isney, Wangen, Munich, Burg Hohernzollern, Heppenheim, Marburg.
Salò, Desenzano, Sacca di Goito, Bancole (Porto Mantovano), Verona, Venice.
Heathrow Airport, UK
Boston, Massachusetts; Connecticut, New York City, Dover, New Hampshire; Newburyport, Massachusetts; Minneapolis, Minnesota; St. Paul, Minnesota; Chicago, Illinois; Los Angeles, California.
This list doesn't include places we drove through or petrol stops, nor does it include brief visits to towns in the vicinities of places we stayed. You might begin to perceive my organisational difficulties and the sheer problem of remembering all the details, let alone boiling it down to a single descriptive sentence and photo for each.
