"Ransom said the oven-bike probably weighs about 300 pounds before he loads it with food and supplies."

"He said it cost him about $500 to build and he spent about $70 on the food for its initial outing. 'It’s all in good fun,' he said. Ransom plans to hold his second event from 8 to 10 a.m. Saturday at Tenney Park. But Bonnie Koenig, Public Health Madison and Dane County’s environmental health services supervisor, isn’t so sure about that. Even though Ransom isn’t selling the food, Koenig said he’ll need to get a license to operate under health department rules, which state: 'Since a mobile food establishment is like a restaurant on wheels, many of the same code requirements for restaurants apply to mobile food establishments, including licensing.'"
