Cleveland possesses an outstanding collection of parks, including Edgewater Beach State Park and Gordon Park along the Lake Erie shore, and Rockefeller Park and the Rocky River Reservation extending inland along ravines leading back from the lake. The city is nearly encircled by woodland parks, with interconnected trails, nature centers, and picnic grounds. To the south, the Cuyahoga Valley National Recreation Area, administered by the National Park Service, is one of the most visited national park units in the country. Professional sports teams in the city include the Cleveland Indians (baseball), the Cleveland Browns (football), and the Cleveland Cavaliers and Cleveland Rockers (men's and women's basketball). In 1996 the owner of the Browns moved the team to Maryland, where it played as the Baltimore Ravens. In 1999 a new football franchise, also called the Browns, began play in the newly constructed Cleveland Browns Stadium. The other professional teams also play in stadiums built in the 1990s: the Indians in Jacobs Field in downtown Cleveland and the Cavaliers and Rockers in nearby Gund Arena. The Cleveland Grand Prix automobile race is held in early summer at Burke Lakefront Airport, which is also the site of the Cleveland National Air Show on Labor Day Weekend.
