Book excerpt: Did you know that Plano once had a winning semipro baseball team? And its own university, boasting a pagoda imported from Malaysia? Or that the city once proudly proclaimed itself the "Mule Capital of the World"? Meet the Native American Planoite who walked in space, the African American entrepreneur who prospered in Jim Crow Texas and the man behind the "mystery stone" uncovered in the Collinwood House. Visit a military tank, a five-hundred-year-old tree and the pioneer cemetery started by a smallpox epidemic. From the town's contributions to World War II to the secrets lurking beneath Collin Creek Mall, unlock the astonishingly large storehouse of Plano's hidden history.
