ARTICLE: "Strict immigration law rattles Okla. businesses: Undocumented workers have left by the thousands, creating hole in economy," by Emily Bazar, USA Today, 10 Janury 2007, p. 1A.

Tough state law "1804" basically makes all the migrant workers disappear, shifting them--I would suspect--to the next state over.

So do employers in OK.

As the state's nursery association president put it: "Some went to Texas, some went to Arkansas. They just left. Those states don't have 1804."

So Oklahoma become a national laboratory in the best American tradition: propose a rule and let it play out.
