Join a Discovery Center Naturalist for an engaging and informative ski on the Discovery Center ski trails. We will look for animal tracks and sign and discuss the physical and behavioral adaptations that enable wildlife to survive the harsh Northwoods winters. Please dress accordingly and bring your own classic skis and boots. Our trails are great for skiers of all levels. Space is limited. Registration is required by March 5. Saturday, 1 - 4 PM. $16 ($12 members).
