Definitaley Ohio St. and Michigan and Army and Navy.

OSU vs that team up north.... not because I live in Columbus (hehe) but because it almost ALWAYS has Big Ten / BCS / National Title bids on the line. ARMY/NAVY is classic, but they always suck. The fans are hype though.

Army Navy is always gonna be #1, but I think you are forgetting Pitt/WVU, which has one of the fiercest rivalries. WVU once killed a Pitt fan, and threw him in the river, saying they were going to float him back home. I've been to a lot of college and pro stadiums, but WVU is the most scary place I visited while watching the backyard brawl.
