Annapolis is also known as the sailing capital of the U.S., situated on the Chesapeake Bay, the largest inland tidal estuary in the world. The Chesapeake is Maryland's canary in the coal mine, troubled for the last 50 years by ever increasing degradation as an indicator of its citizens concern for economic or material value over that of their land. The Chesapeake Bay can not sustain the higher life that once proliferated these waters, and 3 of the main harvests need to be re-stocked by man in order to maintain 1/10th (or less) of the numbers - Oysters and Rockfish, and more recently as reported in the Capital, Blue Crab stocks are at an all-time and ever-decreasing low, with scientists from University of Maryland researching how to raise crabs for re-introduction.
