Lake County, Ohio in the context of "Greater Cleveland"

Cleveland Metroparks is an extensive system of nature preserves in Greater Cleveland, Ohio. Eighteen reservations, which largely encircle the city of Cleveland, follow along the shore of Lake Erie and the rivers and creeks that flow through the region. Referred to unofficially as the 'Emerald Necklace', the network of parks spans over 25,000 acres (10,000 ha) and includes over 300 miles (480 km) of walking, bicycle, and horse trails as well as numerous picnic areas, nature education centers, golf courses, and countless fishing spots. In addition, the district includes the zoo in Cleveland. Four of the reservations are adjacent to Cuyahoga Valley National Park.

Although the majority of the reservations are in suburban Cuyahoga County, Brookside Reservation is located within the city of Cleveland, and the Lakefront Reservation consists of several beachfront parks spanning the city's waterfront. Additionally, three of the reservations are either partially or entirely situated outside Cuyahoga County: a portion of North Chagrin Reservation is in Lake County; a small portion of Bradley Woods Reservation is in Lorain County; the Hinckley Reservation is in Hinckley Township in Medina County.

Ohio's 19th congressional district was created following the 1830 census and was eliminated after the 2000 census. Between 1863 and 1880, it was represented by future US President James A. Garfield, who became the only sitting House member ever to be elected to the Presidency.

From 1992–2002 it included all of Lake County and Ashtabula County together with a collection of eastern suburbs of Cleveland. After 2002 it was replaced by the 14th district. Parts of its old territory were redistricted into 11th, and 13th districts.
