Right, Larry, I should have been more specific... you hit the nail on the head. It's the wording ("rescinding") and bad-taste-in-mouth elitism that bugs me most. For something that's a nice gesture when it stands, it's an equally not nice gesture to revoke it in such an almost bitter way when a park has to modify a ride for comfort or, more likely, safety. (Or whatever multitude of reasons a park could have for fixing up these older rides.)
You know the saying "once a classic, always a classic." I wish instead of revoking the classic status, when parks had to change trains, or any of the parameters that makes a coaster an ACE classic, instead of revoking the designation there would instead be an addendum that said "on X date X park made X modifications..." and make some mention of the fact that even if the coaster isn't running the same way it did on its opening day, the park put in the years. It really seems like the right thing to do. I don't know if that's the solution, but it would seem there should be some middle ground rather than totally revoking the status. It's not really a huge deal either way, but it definitely does leave a bad taste in one's mouth sometimes.
