I lived many years in Corpus, and have visited San Diego and consider relocating to that area. Both have their plus's and minus's.
If you are at all interested in entertainment out side of your boat, Corpus, and Texas in general, is not the place. Heck, just Balboa
Park will keep you busy for days. California
has an openness and a culture built on tolerance that appeals to me though I must say the Bay area is a bit ummmmm, left of my position.
There is no comparison in the food
. If you like BBQ, then Texas is your place. Outside of that you best like cilantro as its in everything. San diego, on the other hand has a wide variety of good foods.
As mentioned above, there will be far less gub'mint interference
in Texas, though that is not always good. Human nature, unchecked by reason, can destroy a lot. Some regulation is necessary. And prices are much better in Texas.
If you are into shooting there is no debate.
Either way, congratulations on beginning the next chapter of your life.
