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.
It was used as propaganda (something used to help or harm a cause or individual) to demand the removal of British troops from Boston. Due to the increasing tension in the city, British troops temporarily withdrew from Boston to Fort William on Castle Island. The British solders involved in the Boston Massacre were also brought to trial.
