This is actually HUGE in NYC. In fact, it makes all the newscasts well before the actual event so people can plan ahead. Quite a few do, as it really is spectacular to see the sun perfectly aligned between rows of buildings on either side. If you've never been to Manhattan, their street plan is laid out like a grid for the most part, which makes it easy to do this. All the Avenues run north/south, all the streets run east/west. So just stand on any street and look towards the sun, and on Manhattanhenge Day you will see it perfectly in place for a gorgeous photo. If you want a slightly different setting, just move up or down the Avenue to get a more north or south perspective. Google images of it to see some amazing views you can acheive this way!
