RIVIERA BEACH, Fla. – Visitors decorated their cars for a hauntingly good time at the ultimate trunk-or-treat experience Friday evening on the Riviera Beach Marina Promenade. Families in their costumes were treated to food, games, music and candy, courtesy of the Riviera Beach Police Department and various other city departments, the Freeman Law Firm and other sponsors. It was among many South Florida trunk-or-treat events over the weekend.
