NBBC is hosting an event as part of New York Hall of Science's (NYSCI) 'After Dark' series, a summer program that leads adult-geared field trips to highlight various activities and organizations around the city. The 3 hour event will include canoe tours, a discussion about the NYC sewer system, and drinks and food by the fire.
The programming is free to the public with a suggested donation of $5-10.
