48 Hours in HaddonfieldA Jersey town embraced as part of the greater Philadelphia region is still a Jersey town — and Haddonfield ranks among Jersey’s Best. One of the state’s oldest communities, Haddonfield dates back to the early 1700s when “West Jersey” was claimed and renamed by Elizabeth Haddon; but one can argue, rightly, that Hadrosaurus foulkii got here first. Make no bones about it: Haddie’s prehistoric skeleton was a landmark discovery in Haddonfield in 1858, proof of life long before the American Revolution and the Quakers came along.
