They say politics makes strange bedfellows . . . but nobody ever said anything about getting in a ring with a bull.

But that's just what Midvale Mayor Everett Dahl says he'll do when he visits Piedras Negras, Mexico, in August to inaugurate a sister city relationship. He said he'll even put on a toreador costume during the town's equivalent of a county fair.Dahl's photo is also to appear on a poster promoting the bullfight.

"During all my work in government, I never expected to get in a ring with a bull," he said. He had thought that getting a cream pie in the face at a community function was bad enough.

The Mexican consulate in Salt Lake City arranged for Midvale to become a sister city to Piedras Negras, a community of about 100,000 people on the border near Eagle Pass, Texas, in the Mexican state of Coahuila.

"They were impressed with the fact that Midvale is willing to support the Hispanic community," Dahl said.

Dahl said Midvale will sponsor a Cinco de Mayo celebration on May 5, Mexico's Independence Day, and has supported other Hispanic cultural events. A representative of Piedras Negras will visit the festival.

As part of the sister city exchange, an Ogden Spanish radio station and Mexican radio and television will exchange interviews of relatives living in the two cities. At least six Midvale families trace their roots to Piedras Negras. An estimated 15 percent of the Midvale's residents are of Mexican origin, Dahl said.

He hopes the relationship will open up trade between Utah and the area, which is a large coal producer.
