If anything, the "newer" generations should get 
more in touch with the incredible history of this team, not 
less, and it seems to me your original post does far more to support 
not mothballing this great historical play than it does the opposite. 
Maybe we should stop teaching our kids about the signing of the Declaration of Independence or the Civil War or Geronimo or World War II or walking on the moon or ... well, you get the idea, (that's all been beyond 45 years). What makes this country great is it's history, (it's no different with sports), and to put a time limit on it would be absurd, IMHO.
