5. Army vs Navy: History, paegentry, and tradition make this one of the best spectacles in the sport. The old school offenses, the students in their dress uniforms, and the post came singing of the alma maters is truly must see TV.
This is my #2. If you go, i'd I'd suggest getting to Philly (or NY, or Baltimore, wherever) Tuesday or Wednesday on game week. There's some much going on before the game. I've seen ships getting commissioned, small unit drills, air assault drills, just generally cool stuff. the fans are some of the best, most respectful fans I've ever come across. The pep rallies are tremendous. Then everyone goes and closes down the bars.
Gameday, get there early (like 10:00am for a noon kick) to see the Corps of Cadets and the Brigade of Midshipman March On - this may be the coolest thing of the day.
You also the trading of "prisoners" (Cadet doing a semester at USNA and vice versa), the delivery of the game ball from someone who ran it from West Point or Annapolis. Then the Golden Knights and Navy Leap Frogs jumping in
Then the flyover.
Then old time option football. What's not to love?
Only complaint would be the piped-in music. The Corps of Cadets and Brigade of Midshipman used to to cheers back and forth throughout the game that would go through the stadium. They still do, but you can't hear them because somebody decided that music was more important.
