Why Illinois is a driving state with almost no public land, and how to use the little there is
Federal agencies manage 414,772 acres in Illinois, 1.2 percent of the state, and the Bureau of Land Management holds twenty of them. The Forest Service has 304,723 acres, nearly all of it the Shawnee National Forest in the far south. The Fish and Wildlife Service has 90,726, the Department of Defense 19,264, and the National Park Service thirty-nine, because its Illinois units are houses and town blocks rather than landscapes. Across the whole state our build of the federal recreation database finds 24 federal campgrounds a vehicle can drive to, and 23 of them belong to the Army Corps of Engineers.
