Does anyone else recognize the other guy (not Marc) in the video? It's Brandt Ruso. He's an advocate for the homeless and travels the country in an old converted veggie oil bus. Really cool guy. He's featured in the documentary of the Jesus for President book tour, called Ordinary Radicals.
And while I was out looking for links, I discovered the Ordinary Radicals blog! It's new to the blogroll, so check it out.
