Book excerpt: Reston A to Z takes young readers on a tour of America's first modern planned community. Your tour guide is Robert E. "Bob" Squirrel, a delightful character who perhaps bears more than a passing resemblance to Reston's beloved founder Robert E. Simon. Told in whimsical rhyming verse, each stop on this alphabetical journey features Bob Squirrel interacting with photos of the places, activities, and nature that make Reston a treasure to kids of all ages.
