personally i would look over several of the readily available maps of the civil war entrenchments all around richmond, and then plot them on up to date city/county maps, and start knocking on doors of private properties that co-incide with much used spots on the old maps...i have found that most large businesses are as easy or easier to get permission from than private homeowners, and usually own alot more land....if you make any large recovery in virginia i would advise you to keep quiet about where you found it for there is a good posibility the nice government fellows will come and relieve you of it........................gldhntr
