Mayor Kimberley Driscoll will be out on the town enjoying the Halloween festivities with residents Friday.

Beginning at 3 p.m. Friday, residents will enjoy discounts or complimentary admission to certain city attractions with proper proof of residency. Valid ID includes a driver's license or photo ID card for adults. Bus passes or library ID cards work for kids.

Museum Place Mall Parking and South Harbor garages will provide complimentary parking to residents after 4 p.m.

"It's a way for residents to enjoy their city just before the revelers come in," said Kate Fox, executive director of Destination Salem, which heads Haunted Happenings.

At 5:30 p.m., beginning at the East India Fountain, residents will have the opportunity to trick-or-treat with the mayor. Captain Jack Sparrow will make a special guest appearance. Many businesses downtown are participating in the trick-or-treating event.
