Manhattanhenge is when the sun aligns with NYC's East-West street grid. It happens twice a year, and in good weather, it's stunning. Unfortunately, this year's Manhattanhenge was a little gloomy and underwhelming, but a ton of instagrammers and twitpicers snapped shots to show what the event was like this year. It wasn't the best, but luckily we get another chance this year on July 12. [Dailymail / HuffPo]
