In late December, my wife, son and I went for a walk to mark the 25th anniversary of the fall of the wall just outside our village. I grew up here, right along the border between East and West Germany. You might be thinking, "But the Wall fell on November 9th, 1989." And so it did, in Berlin. However, I lived along the further westward inner German border--the 870-mile double-barrier of steel mesh fencing, anti-personnel mines, barbed wire, watchtowers and dog runs. The opening here began on December 22nd 1989, with just pedestrian access and only in specific towns.
