I've seen quite a few officials from Southern California and I wouldn't classify them as any better or worse than officials from other parts of the country...except Mississippi.
When speaking of better games to get better quickly you must realize that this can hurt an official as much if not more than help. If you are in over your head too soon, it could stunt your growth and you can continue to make the same mistakes for years.
I can also say with 100% certainty that the west coast has some of the most BS politics in the country. What you wear to meetings, in camps, how you have to "work the room." I love the west coast for some reasons and hate it for others. Politics is something that is brutal out west.
