It is always worth it to exercise your god given rights. However, with all the hoops you have to jump through and the possibility of your vacation being ruined by possible legal issues I would not suggest UOCing on your own. Here in the PRK we have LEOs who will come on up on you with guns drawn and lecture you like you're a child. My suggestion is to just keep it locked up in your car in a small gun safe with the combo off by one number (I always have my firearm with me in this manner where ever i go). Or you can even carry unloaded and locked in a container on your person.
If you let us know when and where you’re going to be here, I'm sure someone would be willing to UOC with you and show you what a pain it is to UOC in CA.
