we were clamming one day,came across these giant holes,at the time couldent figure out what could have made them,told an old timer,he avised us to stay clear of them holes,"a giant stingray with a poisionus stinger could be in one of them holes coverd with silt,get whipped by his tail in the leg,good chance your leg will turn black,you might even lose it".he gave us a 16ft cedar pole with a brass harpoon head attched to a cable and swivel then about 50ft of 3/8ths rope tied to a yellow jug,his last words were"you better make it a head shot"i soon found out why
as for the "scallops"they were good,but the membrane made a mess,realized we were wasting meat,found it was better to grill chunks.
on your hunt,start down tide,look for the muddy water,ease up very slowly,you should be able to sneek right up behind one,get over top of one and drive that harpoon through his head,let him run with the jug,he will settle back down,then retrieve the jug,handline him to the boat,dispatch,haul him in.
DO NOT TRY THIS ALONE,bring one of your Wild Buddys,good luck!
