Bill Swets started making sculptures in 1985, and soon turned part of his farm into the Swetsville Zoo, which has become a major roadside attraction just off I-25 in Fort Collins. But now the property that houses the metal menagerie is for sale, putting the Swetsville Zoo on the endangered species list. In the meantime, though, the free display is still open daily. Don't miss it: This place is a zoo!
