BRIANNA CAPLAN SAYRES didn't know anything about trucks--until her two-year-old son started to teach her everything about them. Now she and her husband put two boys to bed each night in a Seattle home filled with diggers, dump trucks, and fire engines. Brianna has followed the success of Where Do Diggers Sleep at Night? with a whole array of Where Do...books featuring steam trains, jet planes, speedboats, and everyone's favorite diggers celebrating holidays!
