back in the early 60's, like 62-64, while in Germany, we eyeballed a lot of live stuff that made us very nervous. I knew older boys that had a lot of stuff taken from them that could have been very dangerous (and scary.)
Im very careful with my digs. I pinpoint and see how big it is then I also see how deep it is. I dig carefully creating a larger hole around the target area. The area I am hunting during the war was heavily populated with medical fields and camps.
