NASHVILLE, Tenn. -- If you think it just looks cold from inside your warm home, consider the people who have to work outside no matter what the weather is.

Green Fleet Messengers is a bike delivery service in Nashville. It specializes in delivering everything from legal documents to food, and despite these freezing temperatures, the messengers are still making deliveries.

"Our clients are still going, so we're out there delivering for them just like anybody else," said Austin Bauman. "Just because the weather gets bad, that doesn't mean the business stops."

Bauman started Green Fleet Messengers when he noticed gas prices rising. He's said he's proud to call his business the only green courier service in Nashville.
