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.
Reviews for Castle Island Park. We stumbled upon Castle Island and Fort Independence quite by accident. It is a beautiful park and the tour of the fort was fabulous. We had a great tour guide named Jim so if you get to take the tour try and do it with Jim. The park is a very popular place and so parking can be tough. But the walk is great with wonderful views of the harbor area and the city of Boston. If you are in Boston make a trip to South Boston and Castle Island. it is a great leisurely day..... in the city but away from the hustle bustle of city life...well worth the trip.
