It made me think of stories of whole towns along the shores that waited for shipwrecks, then plundered the boats.
Well, sure... but at least they rescued the people too... :-)
Astoria, OR (on the mouth of the Columbia River) was probably built on plunder... being that it got the name "graveyard of the Pacific" pretty early on. Dreadful place, that.
The Columbia river bar is a nasty, nasty place.
