Somehow, I seem to always take pictures of things in their shadows. Perhaps I'm always looking down at my feet (I have a walking problem).

RE: imperiled trees - I just finished reading The Man Who Planted Trees by Jim Robbins. It's about an eccentric gentleman who believes his calling in life is to clone "Champion Trees", i.e., the biggest, broadest exemplars of their species. Not a real page turner, but it's good to know some of the wackos in the world are doing positive things.
