Kenneth "Gene" Eugene Green and Alfred "Dickie" Ernest Green. The community is inhabited seasonally with the majority of its inhabitants calling the Delaware Valley area their home. There are many large families there who have been frequenting the small private beach community for generations. Within the past five years, a small group of members have begun to coordinate events for the community to help raise funds to improve the quality of life at the small resort area. It is a prime location for boating and sunbathing.
