You gotta realize when there is 1 game in Dallas a year, basically every Wings fan in Texas has that one shot to see the Wings without a ton of travel. I live in Texas and still drive 700 miles round trip for the game. I'm not a transplant, born and raised Texan, but I do have roots in Michigan.
I'd imagine something similar happens in Cali, although there are a few games to choose from.
We've had some good rivalries and playoff series with the Kings, Ducks, and Sharks in the past so Cali fans also know it is going to be a good game every time now. I gotta say, though, I moved to the east coast for the nine previous years, and coming back to LA I've noticed that Kings fans are insufferable. Even worse than in the Gretzky era.
