Do me a favor. Go on the treasurenet site and forum Gold Prospecting. At top is one that says "7hr gold prospecting on Lake Erie" from Medina Joe, so he lives here in Medina.
Can you reply to him for me since I am not on treasurenet?
Tell him,
My detecting buddy David in Medina says all the gold in Lake Erie is tainted with high amounts of Mercury and should be avoided. He advises to throw any gold back into the lake to avoid Mercury poisoning.
He will get a kick out of that joke! Thanks, David in Medina
