This book is very simple and easy to read. I liked the rhyme scheme that the author used in the text because it really made the book flow well off of your tongue. I liked this book because you could easily use it as a read aloud and it could kick off a unit where you look at transportation in big cities vs. where you live. In a round about way I think kids would get a sense of what a subway looks, sounds and feels like by reading this book.
