After 85 years they decided it had it's day. It had been rebuilt and redone countless times over the years but they just couldn't do any more work to it. The place was literally falling apart. It was very sad to see it go but it was going to happen sooner or later.
It's just a shame that they couldn't preserve the facade or some such for posterity.
If by the 'facade' you mean the frieze, most of that was gone after the remodeling in the 70's. But if you mean Gate 2, which AFAIK is the only unaltered remaining bit of the *real* original Yankee Stadium to survive the remodeling, there's talk of preserving it for the new Heritage Field to be built on the site.
This reminds me of the Fenway episode of
Cathedrals of the Game. Somebody, I think it was one of the groundskeepers, was taking pride in how historic the place is (as is expected of course). But he went way beyond that. He said something like "fans don't come to games to be comfortable". Excuse me? Now maybe there shouldn't be too MUCH comfort, but neither should there be too little of it. (As I recall, my seats at Fenway were pretty good, in fact.)
You Sox fans may not be expecting me to say anything good about Fenway, but as I said earlier, I had a great time there (the Sox weren't even playing the Yankees in the games I saw). I thought it was a nice place and the food was great. I don't expect, or particularly even want, it to be replaced, but we all know it will one day be... not even this place will last forever. Anybody remember '05? And the only reason the new Fenway was shot down was because the Boston city council wouldn't allow it (the plan was to build a sports complex near the waterfront, with a Sox park and a Patriots stadium). It wasn't a fan backlash that killed the deal.
That being said, one of the WORST experiences I ever had in my life was not *at* the Sox game, but after it. Trying to get into the Kenmore subway station. Worst crowd I've ever been in. Is the construction on that place EVER going to be finished? (I was there a year and a half ago. From what I hear, even after all that time, IT'S STILL NOT DONE!

) I almost literally got trampled to death (and no, I wasn't wearing Yankee gear). I feel sorry for Sox fans who have to use that place every game they go to. Maybe some of you use the 'Fenway' station. I can only hope that's not as wrecked looking.
