Try your luck in Escobar’s Highland Farm’s 8-acre corn maze. This year’s maze, designed by Brett Herbst of The Maize, celebrates the Providence Bruins and features the team’s logo. In addition to hayrides, children’s activities and concessions, Saturday is Harry Potter Day. Those who come dressed as “Harry Potter” characters will receive $1 off admission. Themed festivities include potions classes, wizard tournaments, wand making and a meet-and-greet with the University of Rhode Island’s quidditch team.
