By Karen F. Riley: The Pine Barrens of New Jersey cover 22 percent of the most densely populated state in the country. The name came from early settlers who thought the area was a vast wasteland, but it is anything but barren. Underneath this incredible natural resource lies almost 17 trillion gallons of some of the purest water on earth. The charcoal industry began here, cranberry production, cultivated blueberries were developed in this area. You’ll uncover many forgotten ghost towns but the people who lived and worked there are the real story.
