Yeah, you really have to experience it. When I lived in San Francisco, I went to a couple and that was enough but the best story comes from a game I decided to pass on. A few buddies of mine I grew up with are die hard Jets fans, they come out for a long weekend because the Jets are playing Oakland. He had 4 tickets, I was the 4th but said no -ing way, I am not going. So they go to the game, tailgating etc well my buddy is trying to sell the xtra prior going into the game... well when he is selling the ticket a cop yells at him to stop or to come over as he was suspicious of drugs or scalping, he never really stuck around to see really; he panicked and starting running. Keep in mind he probably had a 12 pack, a couple joints, and a 1/2 bottle of jaeger coursing through him along with the weekend bender to back it up. He is also about 5-8, 155 pounds and wearing either a Mark Gastineau jersey or a Richard Todd one, can't remember. This is somewhere between 1998-1999 I think.
That said, he takes off into what was still a pretty crowded tailgating lot and two cops follow and they are yelling at him to stop... Again, no idea why he took off running, he was doing nothing wrong but he's an idiot. As he is heading through the lot, a couple of Raiders see what is going on and they see some scrawny dude with a Jets jersey and before he knows it two raiders fans with spiked shoulder pads and another with a cape on step in front of him and absolutely lay him out on the asphalt, I mean destroy him. He's lying on his back and the cops haul him off to Alameda county holding cell, where I get the call to come get him. He claims he blacked out for most of it, I don't doubt it but what a story. I was in his wedding a couple years later and threatened to tell the story but obviously did not
