2003. At that time I didn't know much about Penn State. I knew that the players were thugs in the late 90s, but I had respect for Joe Paterno (I bought into his hype, unfortunately), and after 2003 I had heard nothing but praise for their fans. Truly good fans - great to fans of visiting teams, etc. So I liked Penn State.
Then 2005 happened and I thought, "Well, at least they still have a respectable coach." So much for that.
Anyway, I may always remember than 2003 game for how wrong the reports I heard were about the coach. I can't even remember who I heard those reports from - I don't know anyone who would have gone to that game.
