Betsy and Tacy Go Downtown (Betsy-Tacy, #4)

Betsy, Tacy, and Tib are twelve-old enough to do lots of things...even go downtown on their own. There they see their first horseless carriage, discover the joys of the public library, and see a real play at the Opera House. They even find themselves acting in one! Best of all, they help a lonely new friend feel at home in Deep Valley-the most wonderful place in the world to grow up.
