Shellfish warnings and instructions
These days, we've been trained to orchestrate our lives by crisis and regulation. Clam and oyster digging at the beach are now controlled. Warning signs about shellfish (and much else) dot the landscape.
Here on the Oregon sands, harvesting shellfish is regulated and warnings apply. I wasn't trying to harvest anything, just to enjoy coastal views of the dunes.
So I didn't read the lengthy list of Oregon Shellfish Regulations.
