Nana in the City: A Caldecott Honor Award Winner

This book is more of a 3.5-stars for me. The illustrations make it worth it, but the story is a good moral point too. A boy goes to visit his Nana in the city. Is it scary? Is it right for Nana? Are there two sides to describing an environment? I enjoyed reading this one aloud to my littles (5 and 2.5). We live in a rural area so it always an adventure to see a city portrayed.
