According to educators at the Vermont Institute of Natural Science, a great hike should be a workout for your body and your brain. That's why the Quechee nature center now offers a number of free Discovery Packs that families can sign out when they visit. Each pack — donated by Hubert's Family Outfitters in Lebanon, N.H. — is filled with field guides, storybooks, learning activities and interactive games that address themes such as trees, insects, birds and animal tracks. "We want to get [kids] out exploring nature," says Jenna Gersie, a VINS AmeriCorps member, and that's a mission easily accomplished at the center. In addition to nature trails, VINS also offers wildlife exhibits, public animal-feeding times and daily live-raptor programs.
