So I visited Fenway back in 2008 as an Angelfan. It was magical.
I took the Red Line (I think) to the game. All the fans on the train were super cool and we traded verbal jabs with each other. It was something I wish Angel Stadium was like.
Anyway, I got there at about an hour before the game and started talking to fans next to the bullpen for awhile. Super nice people. My Dad and I sat next to the bullpen for the game and even heckled Beckett a little. People were super nice, and even took our picture when we asked them to or told us cool stuff about the Stadium.
The atmosphere there was super cool. I wish I could go back someday to see that beautiful stadium again.
