Speaking of ghost towns, Friendship is one of many abandoned towns in the New Jersey Pine Barrens. It was founded around the 1860s as a cranberry farming town. Cranberry packing finally ended around 1960 or so, and at least some people were still living here into the 1970s. The cranberry bogs are still here.
Coincidentally I visited here about a week after controlled burning by the New Jersey Forest Fire Service, so it was much easier to see many of the old building foundations.
