german ground is still filled with all kinds of explosive matters - bombs, grenades, rockets, bullets, hand grenades and whatever else ...
bombs are found on a regular basis in every major city and each and every time the hazzle with evacuation and defusing is enormous ...
i'm willing to bet that even in the area where i live several duds are buried in the ground as right here is located between two factories (one of them krauss-maffei) and a railway line is pretty close.
my mother told me stories of bombs exploding in nearby gardens, a flak battery right across the street and low flying fighter planes strafing her on her way to school (she was born 1937), there's a memorial wall in the local church tower naming the civilian victims of our area - one of them is a whole family that must have died in a direct hit on their house ... we even have five strange sinks in a clearing in the forest we all take our doggies out - five perfectly round holes, almost parallel to the tracks of the railway and i'm pretty damn sure that some more fell on the clearing and are still there, i just hope that no pup will dig one out one day!
