Maggie and her grandsons spent the better part of each day at a campsite in Colorado while mom, dad and grandpa went mountain biking. Jake was three years old and Max was one year old at the time. The boys wanted her to tell them stories about dinosaurs. She would only tell them stories about friendly dinosaurs. She made up the stories along the way. She decided that her grandsons would identify with the dinosaur characters if they had colors. So, she made each dinosaur in a primary color to go with the dinosaur name. That's where it started. They wanted her to repeat the stories so many times, that she knew them by heart. When she got home from the trip, she wrote them down and thus this book.
