Danica Patrick and Nate Berkus

1 of 15
Atlanta is the next stop on the Oprah's Big Give tour, and Indy racing star Danica Patrick is helping Nate introduce the next mission. "It's definitely going to be hard work," she says. "You're going to have to be driven, determined, competitive and, most importantly, keep your eyes on the finish line."

The challenge has two parts: First, the givers are given $5,000 and a map that will lead them to mystery locations throughout Georgia, where they will perform random acts of kindness for complete strangers. The second part of the challenge is a surprise, but the contestants know to be ready for anything!
