Question: What country does Susan May and Chesapeake Bay have in common?
Context: The Chesapeake Bay Bridge and Tunnel District is a political subdivision of the Commonwealth of Virginia.  It is overseen by the Chesapeake Bay Bridge and Tunnel Commission, and operates the Chesapeake Bay Bridge-Tunnel between the Hampton Roads and Eastern Shore regions of the state.  The District comprises six cities, Virginia Beach, Norfolk, Portsmouth, Chesapeake, Hampton, Newport News, and the two Eastern Shore counties of Northampton and Accomack. The Chesapeake Bay Program is the regional partnership that directs and conducts the restoration of the Chesapeake Bay in the United States.  As a partnership, the Chesapeake Bay Program brings together members of various state, federal, academic and local watershed organizations to build and adopt policies that support Chesapeake Bay restoration.  By combining the resources and unique strengths of each individual organization, the Chesapeake Bay Program is able to follow a unified plan for restoration.  The program office is located in Annapolis, Maryland. Macoma tenta, the narrowed macoma clam or elongate macoma is a species of clam, a marine bivalve mollusk (bivalvia) in the family Tellinidae and genus Macoma.  Macoma tenta are one of two species of macoma clams that can be found in the Chesapeake Bay on the eastern shore of the United States in Maryland and Virginia.  The macoma tenta like their cousin in the Chesapeake, the Macoma balthica or Baltic macoma clam, are small marine bivalves with thin, chalky white shells.  They tend to live buried in the sandy or muddy areas of shallow water in the middle and lower Chesapeake Bay.  Macoma clams are among the most abundant clams in the Chesapeake Bay.  Macomas first appeared about 750,000 years ago. The Chesapeake Bay ( ) is an estuary in the U.S. states of Maryland and Virginia, lying inland from the Atlantic Ocean and surrounded to the west by the North American mainland and to the east by the Delmarva Peninsula.  It is the largest estuary in North America.  With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others.  More than 150 major rivers and streams flow into the Bay's 64299 sqmi drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of Washington, D.C. Chesapeake Bay Interpretive Buoy System (CBIBS) is a network of observational buoys that are deployed throughout the Chesapeake Bay to observe the estuary's changing conditions and to serve as way points along the Captain John Smith Chesapeake National Historic Trail.  They are maintained by the United States National Oceanic and Atmospheric Administration (NOAA).  These "smart buoys" observe and record meteorological, oceanographic and water quality data which can be obtained in real-time by calling 1-877-BUOY-BAY or by logging on to http://buoybay.noaa.gov/.  CBIBS is an operational buoy system in the Chesapeake Bay dedicated to maintaining a broad range of measurements necessary to track Bay restoration progress. The Chesapeake Bay Bridge–Tunnel (CBBT) is a 23 mi fixed link crossing at the mouth of the Chesapeake Bay in the U.S. state of Virginia.  It connects Northampton County on the Delmarva Peninsula with Virginia Beach, which is part of the Hampton Roads metropolitan area.  The bridge–tunnel originally combined 12 mi of trestle, two 1-mile-long (1.6 km) tunnels, four artificial islands, four high-level bridges, approximately 2 mi of causeway, and 5.5 mi of approach roads—crossing the Chesapeake Bay and preserving traffic on the Thimble Shoals and Chesapeake shipping channels.  It replaced vehicle ferry services that operated from South Hampton Roads and from the Virginia Peninsula from the 1930s.  Financed by toll revenue bonds, the bridge–tunnel was opened on April 15, 1964, and remains one of only ten bridge–tunnel systems in the world, three of which are located in Hampton Roads, Virginia. The 2005 Chesapeake Bay crossing study (also known as the Task Force on Traffic Capacity Across the Chesapeake Bay) was a study conducted by the state of Maryland in 2005 in order to explore the possibility of building a new crossing of the Chesapeake Bay.  The crossing would either be an entirely new crossing that would complement the existing Chesapeake Bay Bridge and Chesapeake Bay Bridge-Tunnel in Virginia or would be an upgrade to the current Maryland crossing (by adding a third span). The Great Chesapeake Bay Schooner Race (GCBSR) is an annual schooner race established in 1990 that takes place on the Chesapeake Bay.  The race—held in October of each year—begins just south of the Chesapeake Bay Bridge near Annapolis, Maryland, and ends at Thimble Shoal Light north of the Hampton Roads channel, covering 127 nmi .  Pre- and post-race activities take place in Baltimore, Maryland, and Portsmouth, Virginia, respectively.  Proceeds from the race support Chesapeake Bay education and preservation projects.  The current time to beat is 11 hours, 18 minutes, 53 seconds and was set in 2007 by the schooner "Virginia". The Chesapeake Bay Trust is a non-profit organization established by the Maryland General Assembly in 1985.  Its mission is to support restoration and environmental education efforts that improve the health of the Chesapeake Bay watershed and Maryland's other natural resources.  The organization makes millions of dollars in grants per year.  The organization receives no public tax dollars.  It is funded primarily through sales of commemorative Chesapeake Bay license plates, voluntary donations to the Chesapeake and Endangered Species Fund, and partnerships with other funders and foundations.  Headquartered in Annapolis, Maryland, the organization has repeatedly received four stars (the highest possible rating) from Charity Navigator, an independent charity evaluator. The "Sea Gull" is a Chesapeake Bay skipjack, built in 1901 at Pocomoke City, Maryland.  She is a 46 ft two-sail bateau, or "V"-bottomed deadrise type of centerboard sloop.  She has a beam of 15.9 ft and a depth of 1.6 ft ; her gross tonnage is 10 register tons.  She is one of the 35 surviving traditional Chesapeake Bay skipjacks and a member of the last commercial sailing fleet in the United States.  She is located at Wenona, Somerset County, Maryland.
