Another proposal calls for placing pens along the river bottom and feeding the pigs. Gradually, they would grow accustomed to the offer of a free and easy meal, and would come in greater numbers. Then, one night, the pens would be locked, trapping a large share of the herds. The pigs then would be auctioned or sold to farmers, depending on whether they are healthy enough.
"This would be a humane approach, and it would be time-consuming," said Rosanna Scott, senior administrative assistant to Riverside County Supervisor Melba Dunlap, who represents much of the unincorporated area. "But if we sold the pigs, we probably could recoup the cost. They are very large, and they are probably very tasty."
