Just for grins and giggles and good-natured fun, dress like a witch today and come out to play. Whether your inspiration is Glinda the Good Witch or the Wicked Witch of the West — or a boho hippie witch, join in the festivities as New Harmony welcomes trick or treating in the businesses today from 3:00 to 5:00 and stages its Halloween gold cart parade starting at 5:30 on 10/29, lining up at 5:15 near the former school by Murphy Park and proceeding through town starting at 5:30.
