New SoCal Drone Pilot looking for good spots to fly.

Can anyone give advice on good places to fly a Mini 3 Pro (recreationally) in the Southern California area? I've been caught out a few times driving to spots that Aloft and the DJI Fly app both say are "clear and good to go," only to find out that the city fathers decided in their wisdom to require all drone pilots to go to the police station and register their drones by paying $150 a year or some shit.
