This is a delightful book that all ages will love. I have loved this book since I was a very young child. It's an adorable story about how the farm animals take a ride in the happy man's dump truck. They get to slide down the back whenever the man tips the dumper. He does this each time he greets someone. The animals see how much fun the the first rider the pig is having, so they hop on the happy man's dump truck too! They look like they are having such a wonderful time on that truck. The man featured in the story reminds me of my uncle, so that was an added bonus. I love my uncle, I love the characters in this book and I love this book!
