Let me just start off by saying that the maniacs in sections 327, 326 or 325 (somewhere in there anyway, can't exactly pinpoint it, but its near the Tufts family area) are fantastic. They start chants constantly and are totally into the game. I really wish they were in 329 with me.
Now, save for those guys, the crowds around me for game 1 & 2 have been generally atrocious. I'm not recognizing a lot of people, so I can only assume people are selling their tickets, which is totally understandable since we're all low on funds from paying for playoff tickets. People have been getting yelled at for standing and cheering, but its perfectly acceptable to just walk to the bathroom/concession in the middle of a play.
The loudest the crowd in my area got last night were for the Red Sox score and F!@*%$# KNOCKOUT last night. People had no idea who JoJo or Havlicek were. When the Celts went on a run, they'd be loud, but if they were down, people were sitting on their hands. I don't understand why you'd blow $60+ to sit quietly. People should just save their money if they don't want to yell and watch at home.
Of course as someone mentioned earlier, the games are pretty late. I know with my hours of 6-2:30, I'm completely dead they day after a game, I have the luxury of not caring about my job and only being 25 unlike others though, so I'll scream/yell/chant/clap at any oppurtunity.
Hopefully the faithful come out in full force for game 5, I look forward to seeing the people I saw in the first 2 rounds.
