The sun sets in the middle of street!
Manhattan-what? Here, let's let the director of the Hayden Planetarium explain:
"Next Sunday and on July 13, the sun will fully illuminate every Manhattan cross street (not the curved or angled ones) on the street grid during the last 15 minutes of daylight, and it will set on each street's center line. The sight is breathtaking."
So get your cameras ready, hope for good weather next week, and don't forget to contribute your pics by tagging your photos in flickr with Gothamist!
