Grab the family and come out to see jaw dropping displays of jack-o-lanterns transformed into works of art in the tranquil wooded setting of historic Iroquois Park. A one-of-a-kind experience combining artistry and pure fall fun with over 5,000 professionally carved jack-o-lanterns including well over 100 masterpieces lighting nearly a one-third-mile trail. Grouped in themed scenes and set to music, this year’s show, “A Night at the Library”, is a celebration of the Smithsonian’s 50th anniversary with vignettes highlighting imagery from literature, pop culture, history, arts and cinema. Proceeds from the event benefit the Louisville Parks Foundation. Gates open at 6 p.m. Trail opens at dusk (near 7:30 p.m.). Concessions available.
