No worry over a work permit, no worry over health care, no worry (unless you wanted it, like we did) of being "left for dead" in another culture, so to speak. If we'd wanted to, we could have lived in a base house and shopped exclusively on base for housewares and groceries, and
insulted ourselves as much as possible from the culture. Sadly, too many of my American comrades did exactly that.
Once we got back to the US, I left the service less than a year later, in part possibly because I was in a general funk about not being where I wanted to be, and once that happened, it came down to having to make a living to help support us. Had I been single, I might have been more bohemian, grabbed my guitar, hopped a plane, overstayed my visa, and supported myself playing in the pubs and trading on my obvious wit, charm, and good looks!
