Comments on posts to this blog usually stray far from the topic. In the case of The Best Possible Shield the topic has drifted to DOE foreign travel/vacation policy, with calls for a new top level post. Did DOE buy a "pig in a poke" when they approved this travel to Dijon, France?
Details for Frank:
The rule is that DOE has to approve foreign travel. They generally reject foreign travel if two apparently married people are going, where apparently = same last name. They seldom reject travel if people have different last names.
Married couples with different last names use foreign travel as a way of going on vacations. If you plan it right, you can make it last all summer.
So anyhoo, there is a particular AD [Neu] who is married to a now-naturalized previously-European person. They have used this loophole for about 10 years.
It is a pretty common practice, although this particular couple is really masterful.
