Wear your Halloween costume and watch the parade along Washington Road in the Mt. Lebanon Business District. (The parade runs between Shady Drive and Lebanon Avenue.) At the end, look for the inflatable “Great Pumpkin” on the golf cart, and join in the parade behind the pumpkin. Children may “Trick or Treat” afterward at participating businesses along Washington Road. Be sure to look for the “Trick or Treat” sign in their store windows.
