All is not benign. They also were selling reproductions of American soldier dog tags there - we hope they were only reproductions. Even seeing fakes for sale is unsettling. Families, be prepared.
There is also a General Patton Memorial Museum, see http://www.luxembourg.co.uk/NMMH/patton.html. This is open seasonally, July 1-September 15 - now, surely someone can sponsor longer open times. Take up a collection. Patton deserves better. July 1! We were there in May. Check these dates out, but there is plenty else.
