Why only celebrate Halloween on the 31st when you can have scary fun the weekend before? Dress up and head on down to Hampton Park, where kids 12 and younger can trick-or-treat along decorated, parked vehicles. With jump castles, a costume contest, face painting, hay rides, games, and more, this is a great event for the whole family! Rain location is the Arthur W. Christopher Community Center. Hampton Park. Friday, 4-6pm. Free. (843)724-7327, www.charleston-sc.gov
