Wait, I’m confused, live dig? Where’s the digging? Just take a Probe and feel around for glass…I’ve told you this from the get go. Also you can find out a lot of information yourself by taking the time to research stuff, I know it takes a little investigating on your part but it’s well worth it. Dumps were usually kept away from the homestead and found in creeks, rivers and low lying areas out of site from the homestead. As far as metal detecting goes, start in places where people have been, it’s that simple. Again…this goes with Investigative thinking…..Hmmmm people read books under trees or by their house…maybe they had coins in their pockets that fell out? Maybe they sat on the porch….Try to find some information that will give you a better idea of the average life of the colonial time and after…
