I have never rode in a city bus.  Last Stop on Market Street by Matt de le Pena takes you to that seat on the city bus.  From the bus driver to the blind man and his dog you see what CJ and his grandmother see.  As CJ and his grandmother journey from church to the soup kitchen you listen to  CJ question his grandmother and you love her answers.  This a a great book to use to show students that we all have something to offer those less fortunate.
