Four buildings in Saint Cloud were declared unsafe today after last week's gas explosion. The city's chief building officer says the buildings include two bars, a bail bond's office and a law firm. Investigators are assessing two others including the Stearns County Courts Facility Building this afternoon. It was business as usual in much of downtown Saint Cloud today as people headed back to work for the first time since Friday's natural gas explosion. As work crews continue to clean away debris, the Red Cross and other services are providing counselors for area residents and emergency workers to talk about the tramatic experience. They say the impact of the explosion and loss of life continues to sink in for the Saint Cloud community. Minnesota Public Radio's Kathryn Herzog reports.
