From a JM Spotlight magazine article:
Two JM employees, Joseph Brady and Steve Marce, in their spare time built a large pontoon raft and covered the top with felt from the Paper Mill.
The raft was placed in the Raritan River near the bend opposite the Singer property.
Anchored to one of the largest trees near the river, the raft will be secure when the high water comes.
