Learning that some of their family, that had never been heard of, may be living in Colorado, grandfather Lucas and grandson Mark take a trip from their New York home to find the truth. They stopped in Pennsylvania, Ohio, Michigan, Chicago, Wisconsin, S. Dakota, Wyoming and Colorado to see special sites and keep from going stir crazy just driving and staring at highway signs and lines on the road. They reached their destination and found a wonderful family, a wedding to attend which brought Lucas's wife to the ranch, and a young girl who won Mark's heart. The two families bond as they learn why they had been kept apart and how close they'd become. When Lucas and Mark return to NY for Mark to attend college, the connection continues and their lives become a great family togetherness with romance, growing families and ranch activities.
