Delaware

Delaware is the only state without a single unit of the National Park Service system, although the National Park Service oversees the National Register of Historic Places and Delaware has a lot of entries on that prestigious list.

Delaware is also quite famous as the "best" place to incorporate a business. The state's economic and industrial development have been closely tied to E.I du Pont de Nemours & Company, one of the world's largest chemical manufacturers and distributors. Delaware also enjoys the second highest concentration of civilian engineers in the United States.
