Hey E.T.D....you from Ft. Campbell area? My son was there, and did a little hunting. He's in R.O.K. now, and hunts with me here. I was at Ft. Lee about 28 years ago. It was open, as regards to metal detectors. I found two belt plates on post....one a U.S. oval, and the other a pre-civil war eagle rectangular plate. If they haven't built a new library, then the woods directly behind the old library used to have an old old farm on it. That's where I found the rectangular plate. And I found lots of silver all over Ft. Lee.....some had hunted it in places, but there were plenty of places that hadn't been hunted. Of course, in the last 28 + years a lot could have happened. Make sure and check on the regs, regarding hunting on-post.
Off post....the natives were pretty friendly. Hopewell, VA is right down the road from Ft. Lee.....I lived there. Lots of places near the James River. Most off limits, but a few let me hunt their property.....and had some success. If you have one of the newer machines, then you should be able to find some stuff, even where I hunted.
Then, I did hunt in Petersburg.....pretty much in their Poplar Lawn Park.....I hunted in the late night/early mornings.....like, 11:00 p.m. to 3:00 a.m. It was a pretty dangerous area......I was never bothered, but called the police to help a stabbing victim, and had a few who told me I was crazy for hunting there. I never never hunted that area alone. Well, hope that this helps. And, best of luck. AND, if you are ever assigned to S. Korea, then you make sure you bend my ear, and we will do some hiking/hunting Korean style......and hopefully put a few old coins from here in your pocket to take home. Bill, in S. Korea
