... mmmmmmmm ... panzerkampfwagen....
While I was stationed over there I had a daily courier run up to 7ATC HQ. THe town of Amberg was about halfway. In the middle of town was a parking lot with a sign, "Nur fur PKW". I picked up enough Deutsch to figger that meant "Only for" PKWs, whatever that was; I knew about the PanzerKampfWagen, but this was a civilian urban area.
Turns out it was "PersonalKraftWagen", and "Nur fur PKW" meant "Employee Parking Only".
