Every major city in this country boasts a children's museum with a day's worth of activities for your lil ones. If you've exhausted your local museum, consider a more topic-specific one, like the Crayola Factory in Easton, Pennsylvania. The museum is a showcase of the latest products by the manufacturer, where tots are encouraged to color the day away. They can even see how crayons are made. At the Eric Carle Museum of Picture Book Art in Amherst, Massachusetts, guides children to create images similar to those in their favorite books and offers exciting exhibits and storytime themes.
