Have some friends that grew up on the coast like me who still do it. We like to bring them out let them purge and season,split and roast them on the bbq with seasoning's. My dad used take me to Bird rock in La Jolla in the early sixties and have me tip rocks with a pry bar and a screwdriver for Abs. We use to invade bird rock at low tide and bring home a half dozen big ab's( all we could eat then and left plenty) and pound them out and eat them in the coming evening. After that we would take a hay fork and dig Pismo's where we used to vacation as we as traveled to central Cal to dig Pismo's at Pismo beach. California used to be such a bounty....
