Start your engines and prepare for some spooky fun during Boo Drive Thru, sponsored by Mars Wrigley, a special edition of the beloved children’s trick-or-treating event. Pack your car full of ghouls, ghosts, princesses and superheroes and cruise down the Zoo’s North Road, all in support of Friends of the National Zoo. Supernatural sights await along your drive—and so do treat bags stuffed with M&Ms, Twix and more!
