new to smithing and forum lots of good info. have have gonr through and read a lot but have not seen a answer for my question.I went to my first meeting last weeek. My question the other day I went for a ride and do a little photography and there is a old cement factory shut down about 1970 i walked aroud took some pics and found coal laying around i cpuld pick up several bags. Since this was a industry do you think they used cheap stuff. It is shiney and fist size or smaller. I checked the forum and could not find anything dealing with a find like this. Also is it worth walkin a rail line. I live in western Va and a lot of coal cars go through here goin to the ports .
