I was in the US Army between 1969-1972, stationed in Kaiserslautern with the 69th Signal Company (Photo). I lived with a couple of my army buddies for a short time in an apartment on Beethovenstrasse, our way to relieve us of army routine and to immerse ourselves a bit in the local culture.
While in that Beethovenstrasse apartment, I had friends visit from Paris — Ralph and Deborah — who’d hosted one of my army buddies and me or just me different times at their home in Paris, then Strasbourg.
I suggested we take a walk in the lovely Pfaelzerwald, south of Kaiserslautern. It was during that walk Ralph discovered the possible home of German elves.

Ralph examines a mound in the Pfaelzerwald for evidence of little people…!
In case a little person popped up, we surrounded our friend to defend him against abduction into the dark hole…

Scary! Has to be occupado!
Fortunately, Ralph leaped back in time. Highlighted in the circle, pointed to with an arrow, is my proof of little people — elf! — habitation of this mound!
OMG! I see more and more faces in the mound and above it, not just the one I highlighted! Ralph was in great peril, much greater than we realized at the time!
Whew! I think the German government put a bounty on elves shortly after this photo was taken, and it now is safe to walk in the Pfaelzerwald.
