The Adventures of Lucy and Clark: Yellowstone National Park (Paperback) (ISBN-13: 9781662941757)

Dedicated to those who have always believed in us and encouraged us in our adventures.

Clark and his dog, Lucy, are best friends but sometimes even best friends run of out of things to do. Where will the old box Grandpa gave them, the one that is a lot more than it seems, take the two friends on this rainy afternoon? Where will Lucy and Clark find themselves when they crawl into the box? Who will they meet and what will they learn as they find their way back?
