I know an old farmer in eastern Colorado that has water right to one of the more valuable wells in the state. He refers to it as his retirement plan. What is crazy is that if he wants this water he must drive out to the irrigation ditch at his specified time in the middle of the night and turn on his valve allowing the water to pass through for his designated amount of time. What is crazier is he had caught other famers in the area welding metal over his line to not allow as much water through and therefore giving themselves more water down the line. And these crazy old guys get serious over their water. Apparently it has resulted in random acts of violence and police and court more than a few times.
clean fresh water will prove to be far more valuable than precious metals etc at some point in the future, the way we are going these days. it is life itself...
