Since so many of our ancestors in the rivers, bays, and ocean along the eastern seaboard were engaged in careers as sailors and other seagoers, as well as in farming (the other major natural resource industry!), this was interesting information that helps flesh out the images of life surrounding our ancestors. I am sorry some folks were insulted/outraged/etc., perhaps due to the origin of what is today a common prejorative term. Nevertheless, the products (and byproducs) that impacted the shipping and sailing in that area are quite interesting history in themselves. Karen Carter Minneapolis, MN
