much of your land? >> everything that we had cows on, the grass will be gone. >> this drought is the largest in the u.s. in over half a century, with more than 80% of u.s. farmland being effected. the average cow needs to eat about 30 pounds of grass every day, so when the grass dries up -- >> you want me to get this? >> yes. >> ranchers have to buy more hay to supplement the cow''s diet and the price of hay has skyrocketed. in 2011 kenny paid close to $60 a ton for hay. in 2012 the price quadrupled and it cost him $250 a ton. because of the lack of grass, kenny's had to buy twice as much hay as he normally would just to keep his cows fed. >> i'm pretty conservative about how much they get right now. it's just too much money -- >> that's for sure. >> it's so dry. >> there's so much dust. they were like dried up stalactites in my nose. where are we going next?
