Looking for a fun, free Friday family night activity? Anacostia Riverkeeper is hosting free fishing nights throughout July and August at Washington, DC’s Diamond Teague Pier. On July 23 and August 20, families can learn more about the wastewater treatment process via a hands-on, kid-friendly experiment from the book Wendy, Where Does Our Wastewater Go?  The book, which features Bloom, can be purchased online or at the event.
