TRIBUNE, Kan. (AP) — Only 1,200 people live Kansas' smallest county, where using irrigation to quench thirsty crops is no longer an option for many because the water source underneath this flat, arid prairie is nearly exhausted due to decades of overuse. Recognizing that economic development was at a standstill, county residents narrowly voted five years ago to allow corporate hog-feeding operations to move in and bolster the tax base in the county that abuts Colorado and is named after New York Tribune editor Horace Greeley of "Go West, young man" fame.
