Never have found many, know peeps who do though. They ride back roads and check the road side, my eyes ain`t that good. Have a spot in my front yard where I found about 4 dozen of `em one time. Picked all but left about 8 or 10 for spore purposes. Somebody had other ideas as they took `em, too close to the road. Never found `em there again. Wife don`t like `em so I don`t go outta my way finding them.
PS,
I live by Manistique.
