From 1700 to 1884 duels were fought at the dueling grounds in New Jersey. Dueling was illegal at the time but the enforcement was lax in New Jersey, compared to New York. At times duels were fought at Weehawken at other times at Powles Hook (Paulus Hook), both places are mentioned in newspaper accounts. I am under the impression that anyplace on the New Jersey side of the North, later Hudson River would do.
