Jim:
My dad was in the RCAF and we spent 4 years in Zweibrucken in the late 50's. It was right on the seigfried line and there were many bunkers around there as well. We'd play in them all the time despite warnings not to. At that time there was still quite a lot of unexploded ordnance lying around, as well as other souvenirs in the fields and woods. Great place when you were 10 or so years old, but time puts a different perspective on things now.
This was right around the Cuban missile crisis and I remember air raid drills, keeping a certain amount of food on hand, but by and large we kids were shielded from the political realities of the time.
It is interesting to look back now, some 40 years on, and realize the history that was swarming all around.
