One thing that might be nice is that you could make it a weekend with your mid. 2/C and 1/C are usually allowed to travel independently to the game, so your mi could drive up on Friday and visit with you before they have to show up on Saturday AM. It is mutually beneficial because the busses leave the Yard ~0430. A lot of mids also spend the whole weekend in Philly, so you could get a quality weekend with your DS/DD.
One of my favorite pre-game traditions are the ball run, the flyovers (as much as I cheer against Army that day, seeing their Apaches makes you feel proud to be part of the same team on the battlefield), and the prisoner exchange.
Army-Navy is sort of "going on tour" for the next few years. 2023 will be in Foxborough, MA, 2024 will be in Landover, MD (Washington, DC), 2025 will be in Baltimore, 2026 will be back in East Rutherford, and 2027 will see a return to Philly. That roughly gives both Army and Navy two "home games" each. Philly is considered the designated neutral site.
