As a Yankee fan it is tough to admit this, but I love Fenway Park. Everything about it is great(except the fans). LOL! You guys are right about big games at MSG, nothing could compare to it in 94 when the Rangers and the Knicks were both in the finals. Also, I forgot what year it was, but watching the crowd shot when LJ made that 4 point play against the Pacers was one of the coolest things I have seen. It was pandemonium.
As far as the worst. Shea stadium is an absolute toilet, there are no redeeming qualities about the place!

Camden Yards & the Inner Harbor are nice, but you'd better not go a few blocks in the wrong direction or you might change your mind!!

the area right next to the backside of pimlico is does NOT have boy scouts in it ! there were 2 gang related murders there before preakness 2006.:(

worst for visiting fans any arena in philadelphia and wvu.
