A man wading in the water at the Green Lake Boating Center in Seattle felt a “sharp jab in his foot” Sunday while wading with his family. Pat Boltz reached down and found a metal rod. The rod was sharpened by a machine on the end and it hadn’t gotten there by accident. Nor were the other 38 “spikes”, 2-3 ft. long, found by Seattle police divers.

 

Much to the park police’s horror, someone had planted 39 metal rods in the bottom of the lake near the center and southern docks of the boating center.
