Walt Whitman's house is in Camden, NJ, and his crypt is in historic Harleigh Cemetary in the same city. In the northern part of southern NJ is Smithville, home of the splendidly named Hezekiah Bradley Smith, developer of the Bicycle Railway. The lovely and treasured Pine Barrens that RangerSteve mentioned is the reported home of the Jersey Devil. Exercise caution if you walk in the Pine Barrens at night!
