Winter in the Woods. Join FrOGS and Great Hollow Nature Preserve members for an educational hike and learn about the local flora and fauna that can be found in the winter. The hike will be moderately difficult. Please wear appropriate foot gear, as parts may be slippery. We will meet at Great Hollow and hike parts of their preserve and some of the neighboring Michael Ciaiola Conservation Area. Pre-registration is advised: call Jill at 845-878-9603.
