The ribbon has officially been cut for the new boardwalk trail at the Dr. Elizabeth Yahl Kuffner Nature Preserve, north of St. Marys. Doing the honors Friday, right, are Kris Kuffner, Kurt Kuffner and Kathy Lampert, while Heritage Trails Park District commissioners hold the ribbon. The boardwalk was made possible by generous donations of the Yahl, Kuffner and Hartung families. Along with the Kiwanis Club of St. Marys, the Heritage Trails district is also hosting the 56th annual Walk with Nature Fall Festival from noon to 5 p.m. Sunday at Memorial Park in St. Marys. Festivalgoers will enjoy live music, food trucks, pumpkin decorating and a leisurely hike along the Miami & Erie Canal Towpath Trail.
