MADISON, Wis. -- The winter storm that is blanketing southern Wisconsin Tuesday and Wednesday is sure to make travel difficult, but businesses have to find a way to keep things moving.

"You never know when someone could just hit the wrong patch of ice, and that'll be the end," said Wayne Fisher, a delivery driver for Tony & Marias Italian Pizzeria in Janesville.

Risking one's life for pizza might sound strange, but Fisher said that in big winter storms, it is a reality.

When it snows, Fisher said deliveries pick up. While Tony & Maria's Pizza is making deliveries, they're not traveling as far.

"On a night like this, if we don't have to go out of the area, I'm not going to take that risk," Fisher said. "The roads are going to be bad; they've already made it clear to stay off of the highways. If you don't have to go out, don't."

But some small businesses can't afford to take a night off. The same is true for major corporations.

The General Motors assembly plant in Janesville depends on daily shipments of material to keep production lines moving. If trucks can't make it, officials said they'll charter airplanes.

With a full shift's worth of parts on standby, GM said the concern isn't receiving materials but rather getting people to work safely.

"We are prepared for it; we have enough material," said Craig Johnson, materials director for GM in Janesville. "In fact, our biggest concern is, 'Will there be people here?' I'll have more material than people here if the weather continues to snow bad as predicted."

Locally, there are almost a dozen people dedicated to tracking materials and making sure they get to the plant on time. That means keeping an eye on weather and traffic throughout the Midwest.
