The "Bigfoot" of New Jersey is the 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 the area was mostly suburban homes and open fields, and the canal was now a state park and walking trail so reports of a lone, owner-less, cow wandering a suburban park for decades were greeted with suspicion by local authorities.
On Nov. 23, 2002, a New Jersey Water Authority employee phoned the D&R Canal park office to report that he had seen a cow and it was lying in a ravine not far from the canal. The bull, matching the descriptions of the locals, was too weak to get out of the ditch.
Rescuers finally hoisted him out and he was examined by a local veterinarian determined to be too weak to go on and he was euthanized.
