And We Mean NO!
It started innocuously with a standard sign seen commonly in many places. This place was a parking lot near a lake at McArthur-Burney Falls State Park. In just a few minutes looking around the same parking lot we witnessed all the signs shown below. There were duplicates that I didn't photograph as well.
In the slow turn around we did in the parking lot, we became numbed by all the prohibitions.
Coming up the grade from the lake, we saw this last sign. What irony. Welcome to California.
