A guy told me he caught a 4 foot thresher shark surf fishing at the Gurnet last sum

I believe it. I grew up in Duxbury and there was always sharks being pulled off the bridge. Not dogfish but small 2-3-4 foot sharks. I was on a boat this september and my friend caught a four foot shark on a dead pogie at the end of the plymouth breakwater. Long and fat with big teeth it was a big surprise.
