Georgia Ann Smith, 76, was last seen on June 30, 1999, leaving her son’s home in Champlin, Minnesota around 6:30 p.m., headed for her summer cabin in Minong, Wisconsin — about a 125-mile drive. She was driving a dark blue 1984 Mercedes Benz; neither she nor the car has been located.

Smith had early-stage Alzheimer’s disease but remained independent and often spent summers alone at the cabin. Her family did not realize she was missing until July 4. Investigators followed a few leads: an unconfirmed July 2 sighting of a woman resembling Smith at a Radio Shack in Spooner, Wisconsin, and a mysterious note left at a Wal-Mart by an unknown woman suggesting Smith was alive and being cared for. Her cabin showed no signs of foul play, and her bank and credit accounts were not used after her disappearance.

What can readers who were in northwestern Wisconsin or along the Champlin–Minong route in late June and early July 1999 still remember that might help find Georgia?
