GETTING READY - Police, with the aid of McDonald's restaurants in the area, are preparing for Halloween ghouls - the real kind. Explorer scout Todd Hansen, left, and Ann Arbor police officer Harry Jinkerson test out a metal detector officers will be using Halloween night to check out candy children are given during trick-or-treat rounds. The detectors, which can spot miniature metal particles, narcotics or drug substances, will be available at McDonald restaurants at 2000 W. Stadium Blvd., and 373 N. Zeeb Road, 3811 Carpenter Road, 4775 Washtenaw Avenue in Ypsilanti, 16 Ecorse Road in Ypsilanti, and 7847 E. Michigan Ave. in Saline. The restaurants will also have a surprise for each child.
