With only a couple of exceptions, travel outside the US was inevitably part of a business trip. In 1973, Susan and I spent six weeks in Europe, traveling in France, Germany, Switzerland, and Austria on a Eurailpass. We returned agin in 1975 (Italy), 1978 (UK), and 1984 (France, Italy, Switzerland). In 1998 my son Geoff, my daughter Elisabeth, her friend Andrea, and I toured Germany Switzerland, Britain, and Italy.
I was in China, Hong Kong, Malaysia, and Thailand several times during the 1990s on business. Not much time for photography, though.
Here are archives of those and other trips, organized by country:
