A crisp winter evening is a great time to learn about the night sky. Join us at Grass River Natural Area on Saturday, December 1 at 6:30 pm as we learn about constellations lighting up the sky and then go for a short walk to see what we can identify in the sky. If the weather is not clear, we will use our interactive indoor “stellarium.” This 1.5-hour program is $5 per person. For more information visit grassriver.org. The entrance to Grass River Natural Area is at 6500 Alden Highway, Bellaire.
