What if we could get more water, instead of just living with less? The idea of pulling water from another river, like the Mississippi, has tantalized people in the southwest for decades. We meet a farmer in Arizona who's become today's big champion for this big idea. Also, an engineer in Colorado and someone with an up-close view of the Mississippi explain what it would take to bring more water to the Colorado River states. Part 3 of a 10-part series.
