A group of animal keepers behind-the-scenes at the National Zoo have one of the hardest jobs: ensuring that every animal from the smallest amphibian to the elephants has a well-balanced and fresh diet every day. Join the keepers of the National Zoo's Commissary to see firsthand how fruit, vegetables, and meat are handled and delivered to the entire collection of animals at this world class facility. Tour limit is 15 people, but a smaller group makes for a more intimate experience. Tour to be scheduled for a mutually agreed upon time, and expires April 30, 2016.
