Grandpa and Grandma Purdy take their two grandchildren, Skipper and Katie, on a fun and educational road trip across the United States. The trip includes visits to several historical sites and some very interesting side trips.
Of course, the family's beloved cat, Clarence Christopher Purdy, can't be left behind. Clarence seems to understand everything you say, not to mention he is always interested in Bible reading time.
The Purdys interact with various people whom they meet along their route, and as a result, lives are changed forever. Clarence Christopher Purdy has a few surprises of his own.
