"When the tide is low, the table is set." A blue mussel bed...and a limpet...everything you see here is edible...(chitons and butter clams are plentiful here as well) yet, the risk of PSP (paralytic shellfish poisoning) kind of takes the fun out of it...supposedly in the winter months the red tide and PSP risk is low...not low enough for us to take any risks though...what a shame, i love mussels steamed with a nice white wine sauce.
