Did you know that the open waters of Grass River are a hotspot for waterfowl in the winter? Join us at GRNA on Saturday, February 25th at 10 am as we learn to ID waterfowl and take a hike to the river. This is a free program but donations are appreciated. If you have your own binoculars bring them along or feel free to use some of GRNA’s. For more information visit http://www.grassriver.org/classes-and-programs.html.
