Other Sporting Venues #4 : Second trip to Boston but it wasn't during baseball season

I want to start off by admitting this post messes up the chronological ordering of travelling but to be honest, I forgot I went here back in 2012.  Visiting a city when it isn't baseball season allows me to be a little more creative to get my sports fix.  Boston in the winter only has the Bruins and the Celtics.  Since the Bruins just came off a Stanley Cup the seasons prior, getting tickets weren't exactly in my budget especially since they were facing the Penguins that weekend.  So plan B was to watch the Celtics with their Big Four still intact versus the Knicks with Carmelo Anthony a week prior to Linsanity.
