Greenwich recently celebrated its birthday. The town is either 367, 342, 335, 321 or one billion years old, depending on when you start counting.

The official date commemorated last week was July 18, 1640 when two settlers, representing the New Haven colony, bought Old Greenwich from Native Americans for "twenty-five coates." Much like the famous purchase of Manhattan for $24 worth of trinkets 14 years earlier, it's not clear if sellers were actually the people who owned the land or were merely the ones who happened to occupy it at the time.
