Sagamore Hill National Historic Site is a memorial to one of America's most popular presidents, Theodore Roosevelt. The area is where Roosevelt spent his summers while in office and was referred to as his "Summer White House.” Rent an RV near Oyster Bay, New York, and you will have instant access to this iconic landmark. The site has a variety of landscapes, such as wooded areas, open fields, salt marshes, and beaches (the site is located on Long Island Sound). Roosevelt fell in love with the area as a teenager and documented much of what he saw; his notes were later passed on to the National Park Service.
