I have had a blast even in the nosebleed, standing up "seats". Food and drinks are expensive, but pretty good. I do love a hot dog. (I usually just eat before I go.) I always stay until the final horn. Sometimes I hang around after, but if I go to the parking lot right away I just listen to the post-game on KHTK in my truck while I watch other people idling in line to get out. (Which isn't really as bad as lots of other places I've been to.)
I am emotional...I yell, jump up and down, commiserate or high-five other Kings fans I don't even know. (Some sections seem to have more boring fans, hopefully you'll have a good group around you.) And absolutley you must shout DEFENSE whenever the other team has the ball. You CANNOT yell defense at the Kings too much. Even in a blow-out, they need to work on that defense.
Have fun and I hope they win for you (and the rest of us)
