Where do you dive in Tn. lakes or rivers. I have done alot of diving in alaska, near old cannerys and have found ALOT of old stuff. nothing that I can tell from, before 1850's or so tho. alot of the stuff is early 1900's few go back before that, but they used to just throw their garbage off the dock or pier and everything sank close to where it went in, and have found lots of stuff from all over the world around some of these bigger cannerys, I was just wondering if thats what you are doing diving near old docks or piers. If you ever make it up here, give me a shout .. show you some cool places to dive.. later.. John
