I don't advertise but I live in the area. Raiders games are cool I've been to a couple, it is nuts. Raiders fans are probably more likely to fight with each other than any one else. It was funny one year I went to the OAK/KC game in both OAK and KC the differences in how the fans treat the other teams fans in the stadiums was night and day. I would say don't wear a chiefs jersey unless you want pain lol. In KC they would rib the raiders fans but it was pretty good natured....in oakland.....
....yea just don't wear a jersey unless you go in a group of friends...the bigger the better.
Strangely some of the most violent fights are games between the niners and the raiders....and the niners fans are as big or bigger thugs than the raiders fans.
If you had shown up last weekend you could have gotten to see SF in all it's glory at the pride parade!
