Original poster: "by way of Terry Fritz <twftesla-at-uswest-dot-net>" <BillEaver-at-aol-dot-com> Here in California the insulator spraying trucks come very often (smog) . I got to see one of these operations once and they do break up the long streams of water. Very nice four or five foot lengths of tap water are shot up to the porcelain at a time. It is a neat sight to see! Denis Despins KC6TRW
