Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Mddeming-at-aol-dot-com> Hi Gary, All, Brine (salt + water) eats concrete as well as many metals. It also kills tree roots, shrubs and grass. Burying in the dirt should be adequate. I would use salt only as a very last resort if nothing else worked. Matt D.
