Anne Arundel County is the home of Baltimore-Washington International Thurgood Marshall Airport, commonly referred to as BWI. BWI serves as the main airport for greater Baltimore. It is also an increasingly popular alternative airport to residents of the Washington, D.C. area. BWI is an East Coast hub for Southwest Airlines, meaning that direct flights are available between BWI and much of the country. The southern portion of the Maryland Transit Administration's Light Rail system, connecting downtown Baltimore with BWI, runs through the northern part of Anne Arundel County. The county also has multiple stops on the MARC commuter rail service, including a stop at BWI Rail Station, located near BWI Airport. Amtrak trains also stop at BWI's train station. The Laurel-based Connect-a-ride system operates two routes in the western portion of the county, including Severn, Arundel Mills, Maryland City, Glen Burnie, Hanover, and Odenton. Howard County's Howard Transit Silver route serves Arundel Mills shopping mall and BWI Thurgood Marshall Airport. Sandy Point State Park is located at the end of the Broadneck peninsula near the west end of the Chesapeake Bay Bridge. It features a beach and marina and hosts many festivals and special events throughout the year. Helen Avalynne Tawes Garden is located at the Department of Natural Resources headquarters in Annapolis. The 5 acre garden features representations of the state's various geographic areas. The county also contains some of the easternmost portions of Patapsco Valley State Park, consisting of mostly undeveloped areas of forest and wetlands along the lower Patapsco River. The Department of Recreation and Parks maintains "a comprehensive system of recreational programs for county residents and the preservation of valuable land," including indoor and outdoor sports facilities, community parks, green ways, archaeological, environmental, and historical preserves, and large regional facilities. Some of the major facilities include the Baltimore & Annapolis Trail, Downs Park, Jug Bay Wetlands Sanctuary, Fort Smallwood Park, Kinder Farm Park, and Quiet Waters Park. Other attractions include the Maryland Renaissance Festival in Crownsville, the Maryland State House and the Colonial Annapolis Historic District. Anne Arundel County is home to the two largest shopping malls in the State of Maryland: Westfield Annapolis Mall and Arundel Mills in Hanover in addition to Marley Station Mall in Glen Burnie. Adjacent to Arundel Mills is the Maryland Live! casino.
