Hey Jeff, love hunting those old picnic groves, once you get through the layer of trash, the goodies start popping out. I remembered being at an old, church owned picnic grove before I started detecting, asked a couple people and got a phone number for the caretaker. I called and found out he and his father would be there that Saturday power washing, so after I told him what my intentions were I volunteered to help. After unloading their power washer, cleaning the carburetor to make it run, three hours of power washing and loading their stuff back up, I finally got to hunt. I found SQUAT! Lol...best find was a new dollar coin, some modern clad, a few trinkets and a truck load of beer caps.. (they didn't see the NO ALCOHOL sign)...But, I've had worse days! I got to help someone and got to detect. Like the greenies Jeff, and the presence of the 1800's coinage would usually indicate silver lurking...keep at it! Ddf.
