On a side note,
I like to go hiking on the central Central coast of Calif. at a very large park named Montana De Oro... well turns out that land was previously own by the Army/Navy... and it also turns out the beaches along that part of the coast are very similar to certain beaches in Europe that we as Americans were very interested in back in the 1940's. Thus they did a lot of practice amphibious landings along that stretch of beach.
Last time I was up there they had a big sign saying "the Navy has done extensive searching to remove all munitions however is you see anything like this do not touch it and call this number immediately." They then had a long list of pictures showing some very nasty looking shells, grenades, etc.
