When I reply to people on HN (or anywhere else) I assume I am talking to that person. You noted that "you" (meaning me) should consider taking certain steps. I noted that I don't live in CA. I then pointed out that the concerns you raised about CA apply to the entire US southwest. I then noted that CA has several different climate zones and biomes and that these concerns do not apply to all of them.

What is so hard to understand about this?
