Pine barrens: Pine barrens, pine plains, sand plains, or pinelands occur throughout the northeastern U.S. from New Jersey to Maine (see Atlantic coastal pine barrens) as well as the Midwest, Canada and northern Eurasia.  Pine barrens are plant communities that occur on dry, acidic, infertile soils, dominated by grasses, forbs, low shrubs, and small to medium-sized pines.  The most extensive barrens occur in large areas of sandy glacial deposits, including outwash plains, lakebeds, and outwash terraces along rivers.

Pine Barrens (New Jersey): The Pine Barrens, also known as the Pinelands or simply the Pines, is a heavily forested area of coastal plain stretching across more than seven counties of New Jersey.  The name "pine barrens" refers to the area's sandy, acidic, nutrient-poor soil.  Although European settlers could not cultivate their familiar crops there, the unique ecology of the Pine Barrens supports a diverse spectrum of plant life, including orchids and carnivorous plants.  The area is also notable for its populations of rare pygmy Pitch Pines and other plant species that depend on the frequent fires of the Pine Barrens to reproduce.  The sand that composes much of the area's soil is referred to by the locals as sugar sand.

Griggstown cow: For thirty years there had been a legend of a "ghost cow" that wandered the areas around the Millstone River floodplain and Griggstown.  The cow was seen many times but only on foggy nights or other times of poor visibility, and many tales were told by local hunters and hikers along the canal path.  No spoor or tracks were ever found.  Some fuzzy photographs were even taken, but they were all inconclusive.  At the time area was mostly suburban homes and open fields, and the canal was now a state park and walking trail so reports of a lone feral cow wandering a suburban park for decades were greeted with suspicion by local authorities.  The cow became known as a sort of "Loch Ness Monster" of New Jersey and believed to be a myth, much like the Jersey Devil.
