Just took in the Oakland Raiders beating the Denver Broncos at Mile High Stadium - bought tickets off a scalper for what turned out to be a decent price. Massive 9/11 commemoration before the game - flyovers, paragliders with fireworks, hundreds of cops, firefighters and paramedics, a USMC precision drill, cheerleaders galore, things exploding, the US anthem and America the Brave, etc. etc.
After that the match itself was a bit of a letdown. Ok, I lie, it was hugely entertaining. Pretty amazing spectacle to be honest, it's a silly sport but it's good fun.
