Moments that I personally witnessed: Reich leading a last-minute comeback against the Rams in '89; The Comeback 
  
I wasn't at the '91 AFC Championship Game, but I remember the craziness in Buffalo that night (especially at The Old Pink   ).  I think most people, myself included, thought that that Bills team was invincible, and that a Super Bowl was within our grasp... 
  
Least favorite moments that I personally witnesses: MNF against Dallas last year; Loss in the WC to Jax...didn't realize at the time that it was Kelly's last game.  To me, that game was the beginning of the end...
