For me personally:
1. tOSU 37 scUM 21
2. Red Sox playoff ride (4 in a row vs. Yankees, Game 3 with Pedro which I got to go to, and sweeping the Cards...all moments that are only bettered by the tOSU-scUM game.
3. Madison Mallards win NWL championship over Duluth Huskies in extra innings (only because I worked the game and it was just an exciting game to be a part of.)
What I would consider the Top 3 for the nation in general:
1. Boston Red Sox win the World Series while Yankees choke 3-0 lead away.
2. Super Bowl XXXVIII: Tom Brady and the Patriots win 2nd Super Bowl in 3 years on game ending Vinatieri field goal...again.
3. Ben Roethlisberger shatters NFL record for consecutive wins by a rookie.
(and i'm not including the scandles and all the other crap because that isn't sports...that's just the sports players being idiots outside the lines.)
