Boston Celtics fans seem so much louder than Los Angeles Lakers fans

Is it just me or are the Boston fans much louder than the Laker fans at Staples Center? TD Nanknoth Garden just seems so loud compared to Staples Center! The Celtics fans really seem into the games like it's the only thing they have to do in the city. Don't take that the wrong way, it's great to love your team if you are a Celtics fan and they definitely do have some die hard fans. In Los Angeles the fans seem so much more mellow. Maybe it's because there is so much more to do in L.A. - I don't know. Just a thought I had.
