I think many people wish that the saying "When pigs fly..." were true; so pigs could fly away and leave their destruction somewhere other than the U.S.

War is being waged right now across the country -- against huge, ever-growing packs of feral pigs that are running rampant, destroying crops, killing wildlife and spreading disease everywhere they go, the U.S. Department of Agriculture reports.

They’ve been spotted all the way from Texas to California to Michigan and in New York.

“It's estimated there are at least 4 million of them nationwide, but its impossible to count them all so there may be much more” said Carol Bannerman, a spokesman for the USDA Wildlife Services.

Officials say they cause more than $8 million worth of damage every year. “That amount doesn’t include impact to the natural environment and native species, or to water” Bannerman said. One disease humans can get, she said, by coming in contact with the beasts bodily fluids is called "swine brucellosis," and is extremely painful.
