Vitamin D -- specifically the form D3 -- is the only vitamin your body makes itself. It's fat-soluble, which means your body stores vitamin D in its adipose tissue -- in its fat. And, if you want to be specific about things, this vitamin is actually a hormone.
Sullivan's Castle Island, South Boston, MA, Est. 1951. Castle Island. Located at the end of Carson Beach, on Pleasure Bay in South Boston, Castle Island is a 22-acre recreation site, and the site of Fort Independence. Castle Island was really an island until several land reclamations through the years extended causeways and eventually roadways.
The Pilgrims first landed, however, near the site of modern Provincetown on the tip of Cape Cod in November 1620 before moving to Plymouth. The rock is located about 650 feet (200 m) from where it is generally accepted that the initial settlement was built, on nearby Leyden Street leading up toward Burial Hill.
