News Year's is celebrated at midnight just about everywhere, but First Night --- an extended, New Year's oriented, day-long, city-wide festival --- was started in Boston in 1975 ( http://en.wikipedia.org/wiki/First_Night ). It's been copied in many, many cities and towns since then.
Last night's First Night in Boston was frigid (around 20F/-6C), but fun.
A few smartphone snaps follow; an album and slideshow are available; the latter works best at the "fast" setting.
Happy New Year!
