Some have begun advertising to lure Minnesotans to places where they can eat or drink and smoke at the same time, The Milwaukee Journal-Sentinel reported. Establishments in the Wisconsin's southern tier can expect a similar boom when Illinois goes smoke-free Jan. 1.

Denise Kindt, who lives in Apple Valley, a Minneapolis-St. Paul suburb, said she and her friends drive to Dibbo's, a bar in Hudson, Wis., every weekend.

The spike in business will be short-lived if Smoke Free Wisconsin succeeds in its campaign to ban smoking from public places.

"If there was some surge, which I don't believe, the other surge is more people are going out in Minnesota because they can," said Maureen Busalacchi, the group's executive director.

A bill banning indoor smoking is before the state Senate.
