Returning to the scene of an earlier winner - foliage had grown and encroached on the scene. This is the earlier ribbon winner - http://www.pbase.com/ed_k/image/45602044 however getting closer and zooming more might have produced about the same image as before.
Notice the 30 second exposure time (opaque screw-in IR filters can take a while, especially in low early morning light and a stopped down aperture). Notice the sharp foreground vegetation - a sign of the still air.
