Ask This Old House

In this special episode, the guys tackle practical solutions for drought. Richard and Kevin open the show at Lake Mead, the largest reservoir in the country that's only at 40 percent capacity. Roger visits Las Vegas to replace a water-guzzling lawn with a desert appropriate alternative. Kevin meets with meteorologist Jim Cantore to hear cautionary tales from the front lines of the drought. And Richard travels to San Francisco to replace an old-fashioned toilet with a new "water sense" solution.
