boardwalk spans over thirty blocks, containing carnival rides and games, restaurants, bars, arcades, and clothing boutiques. Tourists visit St. Michaels on a neck surrounded by water; the colonial former port of Oxford; Chestertown; and isolated Smith Island in the Chesapeake Bay. North of Crisfield is Janes Island State Park, with camping and kayaking trails through marshlands. Fishing At the southern end of the Chesapeake coast of Maryland, the town of Crisfield is home to a fishing, crabbing, and seafood processing industry. Agriculture In the 21st century, the main economic activities on the Eastern Shore are vegetable and grain farming, seafood, large-scale chicken breeding (Perdue Farms was founded in Salisbury and is still headquartered there today), and tourism. Tobacco was the chief commodity crop during colonial times. The agricultural economy switched to mixed products, including grain, in the second half of the 18th century. Energy Energy in the Eastern shore is provided by five oil and natural gas plants. Pipeline Environment As part of the broader Chesapeake Bay watershed, the Eastern Shore confronts common environmental issues of the watershed, such as nutrient runoff from agriculture, but it is also vulnerable to climate change. Because of its low-lying geography and sandy soil, the region is particularly vulnerable to sea level rise and salt water intrusion. Moreover, because of the coastal geography, infrastructure is already being damaged both due to sea level rise, and storm surge from tropical storms and hurricanes. The Eastern Shore’s economy depends on the larger fisheries and farming, both of which are sensitive to climate change. Transportation Various waterways provide a medium for commerce and boaters: the Atlantic Ocean, Chesapeake Bay, the Susquehanna River, and the Chesapeake and Delaware Canal. There are three major routes to the Eastern Shore: The Chesapeake Bay Bridge spans of the Chesapeake Bay, and at the time of construction in 1952, was the longest continuous over-water steel structure. A second parallel span was added in 1973 and a third has been discussed, most recently in 2006. A third span would not open, according to state officials, until about 2025. The bridges have eased commuting to larger cities. Kent Island, site of the first English settlement on the Shore, has become a bedroom community for Washington, DC; Annapolis, and Baltimore. Kent Island is part of Queen Anne's County. U.S. Route 13 Maryland Route 213 The two major highways on the Eastern Shore are U.S. Route
