I have a friend who lives on a ranch in the wide-open spaces of Montana. The road to his home is a long trail that winds through the parched and barren landscape of the wilderness. As you drive toward his home, you can’t help but notice the contrasting strip of green trees and vibrant vegetation meandering through the ranch. One of the finest trout rivers in North America cuts through the property, and anything that grows near its banks gets the benefit of an unending source of vital water.
