Rep. Peter Welch joins us to open the show with an update on what’s happening in Washington. Then we learn about dowsing from a member of the American Society of Dowsers based in Danville.  After that, national correspondent Bob Ney provides his look at national and world events. We follow that by hearing from Kevin McCallum of Seven Days about concerns for the health of Lake Memphremagog. And then author Celia Ryker shares some of the stories from her new book “Walking Home” that chronicles her hike of the Long Trail from the Massachusetts to the Canadian border.
