“one of the triggers appears to be a heat sensitivity. “
In that case N California is still your best bet for the climate you need.
Climate, yes, most probably. The ability to purchase firearms? No. See previous about dealers refusing to sell to Californians, not to mention mandatory registration along with a 'wait period'. However, I am not a convicted felon so that is a plus. So far...
Oh, I should add: if I am going to be required to apply for a new DL, I might as well do it in a state that will no longer have Firearms Dealers refusing to sell because of where I live. I might as well change residences now while I am required to undergo the documentation challenges, and physically relocate if these ridiculous “registration” requirements are not immediately repealed as invalid law.
