You have to conclude that Fenway is it...albeit more like "The Chapel of Baseball". I'm fine with that. I admire the tenacity of Bostonians for showing up to save their home when the wolves came.
Does baseball need a "cathedral" on principle? A home? There was no question about that when Yankee Stadium was standing. So much of baseball history coalesced in that single building. Most people couldn't fathom Yankee Stadium being disposable, but we've been proven dead wrong, obviously. Where is baseball's physical/tangible home now? And please don't say Cooperstown.
PS--Was watching a home game the other day and Michael Kay was discussing something or other about some significant games 40-50 years ago. Then he said, "That all happened right here at [hesitation] Yankee Stadium." Almost puked.
