If you heard lots of thunder-like sounds in the NYC area tonight (and even Upstate NY too), this is why.

New York was celebrating the quadricentennial of Henry Hudson discovering New York City. Yep, about 400 years ago, Henry Hudson sailed along parts of what is now the Hudson River and helped support the first settlers in the area.

UPDATE: Ok, I stand corrected. The fireworks I heard last night were for the Hoboken Italian Festival. However, the video above is for the quadricentennial fireworks.
