Boo at the Zoo

Please note: This event has already occurred.
Pint-sized zombies can get decked out and hunt for treats (and, naturally, brains) at the National Zoo's 14th annual Boo at the Zoo. The after-dark event features trick-or-treating for kids ages 2 to 12, each of whom will get a bag to fill up at treat stations; also on tap are plenty of Halloween-themed animal events. 2 to 12.
