The Thanksgiving Day Massacre, otherwise known as Alice's Restaurant.
Ann and Keegan told us that there is a tradition in their family that on Thanksgiving they played a recording of the song titled Alice's Restaurant by Arlo Guthrie.
You see, it all took place on Thanksgiving. "We loaded the VW microbus with shovel and rakes and implements of destruction and drove off to the city dump." "When got to the city dump, there was a chain across the front of the city dump, and a sign on this chain said 'This dump is closed on Thanksgiving.'" And that is how it all started.
