"River on the Go: Where Is Justin the Beaver?"

In 2014, the Bronx Children's Museum will open its Kids' Powerhouse Discovery Center in Mill Pond, across from Yankee Stadium. Until then, the "museum without walls" is touring the borough with its interactive environmental exhibit, housed in a refurbished school bus. Little ones who climb aboard the vehicle will discover the sounds of the Bronx River and join in a hunt for flora and fauna. All ages.
