Is Dallas the best AMP scene in the country?

I'm moving to San Diego in the next few months and I am wondering what the AMP scene is like in that area and also what it's like in Las Vegas. The info I get on ECCIE is substantial in the Dallas area. It is not nearly as substantial in San Diego or Las Vegas. Is there another site I should use for those areas or is there just substantially less available in both areas?
As I'm a provider who hasn't worked in an AMP and otherwise know very little about them, I'm sure other hobbyists could provide better intel. With that said, are you familiar with http://rubmaps.com

...might at least be a starting point
