Airline-issue eye masks -- travel never used to be part of my job (except for a short period of monthly one-day visits). And I was happy with that.
But in 1995 my employer asked me to become expert in a new technology and join its technical committees. I had no idea what was ahead.
It took almost a year before the travel began, with a 1-day meeting of the main committee in San Antonio. Three months later I attended the 2-day kickoff of my ISO committee in England. (It's funny to recall now and colleagues laugh at the story, but I was so very stressed about that: "OMG, I am going to a really foreign country!"*)
It began to pick up after that, with the main committee soon going from one to four meetings a year (and from the original 1 day to as many as 7-1/2, though we're back to 4-1/2 days) and the ISO meeting 2 days each year with a different member country playing host.
A bit of travel but manageable and the formation of a third committee in early 2000 with up to four more meetings a year (usually tacked on to the main committee's meetings) didn't change it much.
But for me that all changed late 2000 whenI flew to Beijing to speak at a Chinese government committee meeting during a conference there. (I even had to get a suit for the occasion.)

The annual international meetings continued, including Canberra, Seoul, Paris, Cairo and Key West among our venues. Kathy and her languages sometimes came with me; otherwise I was learning to manage on my own. (Herr Rose at Central Intermediate would not be pleased with my 30-years-rusty German.)
A few years later I started speaking at conferences domestic and international: New Delhi, Mexico City, Vienna... well, there's a lot more but you get the idea. I also wound up a member of a European manufacturer's association, thereby adding more travel and speaking engagements -- and more countries.
I think such travel unavoidably and irreversibly changes one.
In a comment to a previous posting girlsinger wrote, "Some told me they couldn't wait to leave [Midland] and some, like you, ... hoped to stay." Yes I did, and for a very long time, but I am not sure that's the case anymore.
Observing so many other cultures and learning a little of their ways, I started seeing the world, not to mention my own culture and home, differently. Today I might well be one of those who couldn't wait to leave Midland. And for all that I still feel most at home in the Midwest there are a few places abroad I would very much like to try to live, places to which I feel a significant affinity, even though they all require learning a new language. It is possible to do; Kathy knows Americans who "went native" abroad and remained.

I thoroughly disagree. Though you can never go home again, you carry a bit of home with you forever. And if I were to go abroad to live in another culture and to learn new ways, a little bit of the Midland of old would go with me.
