Shooting from a vehicle is not against the law for everybody in California. If you qualify as a handicapped hunter you can shoot from your vehicle. It is also legal to light from your vehicle in certain areas of the state as long as the vehicle is off road with the motor off. I have a handicapped friend that makes stands and lights from his truck. His truck is a killing machine, it's nothing like a Texas setup, it's totally different.
I was there for the 65 Watts riots, lived right off Imperial and Western, it started on Imperial. The last burning contest they had I was working at Danial Freeman Hospital about a mile away from where it started. Yes I had a gun in my truck and I made sure everybody knew it, I also made sure everybody knew I was a varmint hunter, a dirty nasty critter killer lol.
