Had a CHP pull me over one afternoon...had me dead to rights, speed, oil and dust totally obscured the license plate on the truck, no seat belt, cracked windshield, yada yada. In rooting for my drivers license, I set my NRA card on the hood, he picked it up, well, that's good enough, get all this stuff fixed and slow down, have a good day. It was.
Modoc SO, pulled me over for no license plate lights near my house. Asked if there were any weapons in the car. I told him about the CCW permit and pistol in my pocket. His reply:
"You keep yours in your pocket, I'll keep mine holstered".
That doesn't generally happen in the bigger Cali cities.
