For what its worth, the term "Submarine Races", was originated by Murray Kaufman and Cousin Brucie in reference to the 'necking spots' (the Alpine Lookout mostly) on the Palisades Interstate Parkway overlooking the New Jersey section of the Hudson River. There were two such "observation" places, Alpine and Englewood.
After a while the PIP Police became pretty diligent and cruised the lookouts fairly regularly, wrecking them for all of us who were growing up in the area at the time.
But, as with all things, time has taken the toll of the PIP Police and the lookouts are no longer as safe as they once were.
