As an Army brat in Schwanheim, Germany in 1949 my friend and I found un exploded bombs in the wood......We must have been about 8 years old.
But Darwin Award candidates that we were, I remember we lifted these about fifty pound bombs up and dropped them!
Brilliant
I met a couple of teenagers in Swiebrooken that explored old bunkers and connecting tunnels of the Siegfried line in the area. The GI’s had blown up and fenced off the bunkers because of booby traps and they were all over grown with brush. They both had real nice MP-40’s.
