My grandson was saying it's a very 'upscale' area. I asked about the green fees and he said it's $200 to $300... which is less than I would have guessed.
About that area.... In Oregon, and Northern California, they have tsunami escape routes. I've never noticed that in the LA area BUT.... it could have EASILY escaped my attention. Do you have signs marking designated routes?
I seldom get south of Disneyland,

, so I know little about that area. I'm always traveling on "Google Earth" and one of the great mysteries for me is that great expanse of mountains between 241 and 15. Looks very interesting, on Google Earth... especially the Black Canyon area. - JamesJM
