The fall of the Berlin Wall, part II:
As word spread out across both East and West Berlin concerning a new travel policy by the Eastern Communist government, thousands of Berliners on both sides of the wall inundated border guards at multiple checkpoints. People started climbing atop the wall and demanded that the guards open the gates.
28 years after its construction (back when JFK was President), the Berlin Wall was now obsolete.
November 9, 1989 - 22 years ago today.
