It was a pretty day today. The weather has finally turned cool and it’s clearly autumn now. The leaves on the trees are still mostly green but there are occasional splashes of color from early maples or some of the smaller plants that tend to react more quickly to the changing seasons. Outside my office window, the Virginia creeper (Parthenocissus quinquefolia) is a deep red, climbing up into two large elms and the other trees on the edge of the woods. Cathy and I met at a picnic table briefly early in the afternoon and then I walked in the woods and took a few pictures, including this one of the bark of a black walnut tree (Juglans nigra).
