This picture book presents many interesting facts about the development of transportation infrastructure and technology.  It starts with the building of the National Road and early trains and moves through the development of bicycles, cars, and the U.S. highway system.  The story circles around on a regular basis to those who were opposed to the development of this technology along the way.  On the last two pages is a very bleak look at the effect of transportation technology upon our environment.  The final page mentions the types of clean burning technology that is being worked on by “a pack of crazy thinkers”.  I think that the sarcasm of this book will be lost on the young audience it targets and they will be left confused.  The illustrations are bright and engaging.  In fact, the cover is what initially drew my attention and made me interested in reading the book.  I would have preferred a more positive approach to the history of transportation technology.  Covering the resulting environmental issues is a good idea, but I think that a straight forward approach would be less confusing for children.
