This endlessly readable book covers every inch--geographically, culturally, and historically--of the Keystone State. Uncle John profiles a wealth of Pennsylvania firsts--it is home to the first U.S. zoo, first in the nation in mushroom production, and the leading producer of potato chips and pretzels. How common is a state dog, drink, or soil? Pennsylvania has all three--Great Dane, milk and Hazleton, respectively! Quizzes, puzzles, games, mini-bios, whodunits--all can be found in this fun book that's perfect for a solo or group read.
