When I was a kid ,(a long, long time ago) my dad took me to Camp Nichols, where we got permission from the land owner. I used my low-end metal detector. I found a Minnie ball (I think that that's what that type of slug is called,) a soldered can lid, a forced padlock and several links of brass chain, and some pieces of old bottle glass. I don't member if there was anything else. I still have the stuff. I have wanted to return out to the present land owner or to a museum.
the museum in Kenton is a nice little place.
