The Miami Valley Trails are open daily and can be a beautiful way to experience the winter outdoors. But who are we trying to kid? There isn't any way around it: the 2013-14 winter has been brutal in the Miami Valley - as well as many other parts of the United States. The National Weather Service reports total snowfall for Dayton to be 45.3 inches for this season - a whopping 28.2 inches ABOVE NORMAL through February 17th. And it hasn't just been snowy - it has been cold.
