Your right on both... 1565 and some great fishing. Its the oldest continuously occupied European settlement in the continental United States. It also has history going back to paleo..and is a hot spot for fossil shark teeth and other fossils.
I'm really hoping someone might tell me something like..."I found pottery chards on such and such shoreline" or metal detected some musket balls here... I'm actually staying real close to a fort site with a fresh water spring... I suppose that should be all I need to know.
