Transcript
Welcome to the Treasures of Jamaica Plain. Within the walls of this time capsule, you, our descendants, will find the items and mementos we treasured in the year 2077. To you, two hundred years in the future, these relics may seem quaint. But we hope that they will remind you of our place in history, and your own. As we laid the foundation for the world in which you live, so you too will lay a foundation for future generations. May that future be bright. On behalf of all of us in 2077, we wish you well. This is Mayor Alyssa Park, speaking for the town of Jamaica Plain.
