Michigan Badger, was that park in western Michigan happen to be Centennial park in downtown Holland? The park where they hold the huge tulip festival? If so, there was an old lady(she was in her 90's), across the street who would call the cops everytime she saw anyone detecting in that park. The cops would come out and say, (just to keep the peace) that it was illegal to hunt public property in Holland, then proceeded to tell me to go to the local school yard. I asked them if it was a parochial school and they said NO, it's a public grade school! Go figure. Any ways I was getting I.H. pennies everywhere, only 1/2 inch to 3 inches deep, Barber anything, everywhere. So I went to my sister's house in town, and made a picnic lunch, and asked my sis if she wanted to go for a picnic in the park. After I explained my situation to her, she said let's go for it. I used to own one of those Garrette hand scanning, body searching metal detectors. I also told my sis that make sure it was a blanket she no longer wanted. When we got to the park, we laid the blanket down in the area that I had been hunting. You guessed it, yup, uh huh, right through the blanket

. All I used for retrieval was a thin bladed screwdriver, and never damaged any coins. We followed the shade that day, and I got over 200 old coins, silver included. She called me after a couple days and said she was keeping the blanket for my return, she said she calls it her Cathlic blanket because it was so "Holey".........NGE Oh and you couldn't see where I had been digging when we moved the blanket.
