Best Parks to See a Game---or Best Fans

What are the best places to see a game? NOTE!!! I'm not referring to the quality of the stadium, comfort of the seats etc. But instead, which teams seem to have knowledgeable respectable fans?

This is in response to someone's comments about how Yankees/Red Sox games, while offering a great rivarly, are not the best games for family or good quality fun, partly because the fans are so roudy.

Now, this is almost a test to see if we can make comments without being insulting!
