Manhattanhenge http://en.wikipedia.org/wiki/Manhattanhenge 'Manhattanhenge sometimes referred to as the Manhattan Solstice is a circumstance which occurs twice a year, during which the setting sun aligns with the eastwest streets of the main street grid in the borough of Manhattan in New York City. The neologism is derived from Stonehenge, where the sun aligns with the stones on the solstices with a similarly dramatic effect. The word was popularized in 2002 by Neil deGrasse Tyson, an astrophysicist at the American Museum of Natural History.'
