The Great Allentown Fair, Aug. 28-Sept. 3, brings the summer season to a fun, entertaining and educational close with a lineup of Grandstand shows, farm exhibitions, arts and crafts contests, culinary demonstrations, midway rides and more at the Allentown Fairgrounds 17th and Chew and Liberty streets, Allentown. This year’s 166th edition of the Allentown Fair is sure to be another Lehigh Valley classic.
