MADISON, Wis. (AP) – The state Department of Natural Resources plans to host an online chat on snowmobile safety.  The chat is scheduled for 11:30 a.m. on Friday. Gary Eddy, a DNR conservation warden and the agency’s snowmobile safety administrator, will be available for questions. So will Diane Conklin, the DNR’s snowmobile grant manager.  Participants can register for the chat by visiting the DNR’s website and searching for the phrase “ask the experts.”
