Interpretive Naturalist Rose Nevil, at the left, was the leader of a Tree Trail Hike at Ouabache State Park on a recent Tuesday evening as the park and the Friends of the Wells County Public Library offered the opportunity to folks of all ages. Hiked was the 1.5 mile trail that now has tree markers, like the one at the lower left in the photo, that help with identifying some of the trees. Leaves have just begun to change colors at the park.
