hi canewrap. urban sprawl is our biggest enemy - new houses, roads and subdivisions go up everyday. very few relichunters up this way i've heard of use the or's anymore. i live about 5 miles north of petersburg, va. and it's been pounded a lot too. it's hard to find a virgin spot, but theyr'e out there. most of the guys around here see a new road, new subdivions or a walmart going up, and immediately start following the dozers and detecting the site. dirt piles are the instant attraction. the google books feature jigflipper talked about is a great resource, as is your state's historical society civil war era map collections. both are free, and it might surprise you what the historical society has in maps. ours is just amazing. seeing and reviewing these old maps, and comparing them to newer maps will put you on the right path.
i gave up on going to the most obvious sites long ago; most have been pounded to death, and a lot are protected by the park service, so i can't go there. i quickly found that i find some good stuff near battlefields and water sources, and some were virgin sites. i'm always surprised at finding cw relics around old houses too. i've always thought that all ground is good ground. the ol' boys with the minesweepers back in the 60's and 70's beat us to a lot of the big brass relics [like beltplates] and shells. so, with all this in mind, wer'e always looking for anywhere to go in the area...exactly where really doesn't matter to us. nice relics are often found in the most unlikely places. we just get our coils to the ground anywhere we can.
canewrap, are there any big fields or woods near your house? try to hunt them and see what you come up with. old houses often give up a few relics too. your're in a prime civil war area, and so is jigflipper. don't forget that no one man or machine gets or finds it all. good luck my friend, and let us know how you do. hh,
