We went to Boston last season, and we went on a tour and saw a ballgame at Fenway. You're absolutely right that the seats are small and cramped. During the entire game I had a love/hate relationship with Fenway. I was in awe of place, but my knees hurt from the constant twisting and turning and I had no shoulder room. Still, that place is simply awesome.
Also, here's a story from the tour that I think you and other folks from the BRM era would appreciate. Our tour guide was probably in his 60s, a lifelong Red Sox fan and a terrific storyteller. He weaved in stories about the park in with each section that he showed us, and it was probably the best tour I've ever been on for anything.
Anyway, when we're out in left field he begins to tell a story about Fisk and the Game 6 home run, concluding the story by showing us where the Fisk home run hit the foul (fair) pole. I'm standing there with my Reds hat on, just grinning through the whole story. When he finishes, I raise my hand and he asks me if I have a question.
"Can you show us the exact spot in center field where Joe Morgan's base hit in the 9th inning of Game 7 landed?" I ask.
He looks at me for a quick second, then with a slight chuckle said "Our Reds fan has decided that the tour is over early for all you folks. Have a nice day."
