Retired civil engineer turned author, Russell King, has created "Have You Seen My 18 Wheeler?" a series of picture books about 18 wheelers. For Book 11, he photographed 19 trucking firms with 7,270 tractors.Do your children realize that everything we use in America is hauled at some point in an 18 wheeler? Think about it - those paper towels traveled from Green Bay, Wisconsin to the store in New Orleans. The fruits and vegetables came from a warehouse in Bakersfield, California to Omaha, Nebraska. That WMTA public transit car in Washington, DC came from Clackamas, Oregon. All on trucks ! !Russell's remarkable idea grew from his experiences as a civil engineering inspector on interstate highway and bridge construction. He was standing on the highway, sometimes within inches, as these 18 wheel behemoths left a rush of air in their wake as they rush from point to point. And then, as he and his family drove those same interstates, he wondered how many they met on the trip from Chicago to Hilton Head Island.

He graduated from Iowa State University with a BS in Aerospace Engineering and retired as a civil engineer 45 years later. You've often heard the expression -- but he can honestly say "Yes, as a matter of fact, Aerospace Engineering really is Rocket Science".
