I spent some time in Germany around Frankfurt-am-Main in the 60s, but strictly as a civilian.
I was there from 77-81. Thanks to the Army, I got two trips to Crete, a week in Oberammergau, and a 3 month TDY to Northern Germany, about 30 miles east of Kiel.
They had to drag me out of there screaming and kicking. For a variety of reasons, I've never made it back. Hopefully, my employment situation will improve so that we can see "The Passion Play" next year.
