An observation to share about buried radials surfacing is, It surely has to happen and it's likely impossible to predict where & when they'll do that.
I metal detect and sometimes in never plowed sites, find ancient coins near the surface and modern coins 12" down in the same area. It happens this way so often, I just can't reliably predict age by the depth on the detector screen. Some sections of buried radials will someday, probably surface. 73, Gary KA1J _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
