After doing the Valley Forge pic, I wondered what Earth would look like as Lowell knew it. Picture huge catterpillar tracked vehicles searching the planet for the remaining drinkable water. I have in mind the crew of this vehicle coming across an oasis with dead trees and shrubery and some cracked mud that is all that remains. What I really need is those dead trees! If anyone can point me in the right direction, I'd be gratefull.
