Cigarette butts, fast food bags, used diapers and bottles full of urine are all in a day’s work for the Department of Ecology’s Youth Corps, which works through mid-August to clean up Washington roadways. More unusual was the pipe bomb found by a crew working in southern Washington last week. “They find all sorts of things along the roadside,” said Jani Gilbert, public information officer for the Department of Ecology’s Eastern Washington Office. “The pipe bomb was obviously very dangerous, but no one got hurt.” Car parts, blown tires and bags full of garbage are more common and not quite as potentially harmful items.
