Going to pot
Farmers in Maricopa County, Ariz., may harvest an unexpected crop this summer. Thanks to an unknown culprit who dumped more than a ton of freshly harvested marijuana into an irrigation canal, millions of seeds could find their way onto cotton farms. Steve Werner of the county sheriff's office said 1,500 pounds of pot were retrieved from the canal. But he estimates that 500 pounds floated past drug-enforcement officials.
