I never laid eyes on these individuals, but their work was in evidence everywhere. It is amazing to see how much life is supported by these guys. Fish, fowl, insects, and large mammals are some of their dependents. You cannot help but think, what have I done to support life on the planet? How big a mark will I make, and will it be red or black? I was looking at this from a clearing in the forest. What I mean to say is, they even provided the sun on my back. Damn!
