I know everyone says that and I'm sure it's true - I know people have drowned - but I've swum on every beach from Great Bay to Billy's Bay (except that one by Jack Sprat lol), and even with big waves, no problem. Often it's like a bathtub.

I do swim well and grew up on the east coast - beaches on Long Island, Cape Cod, etc - much much stronger undertows and waves than JA.
