How do I deal with this awkward situation?

Wednesday I have to go to a meeting for work about 150 miles away. It’s probably going to be five hours total in drive time and a six hour meeting. I have to go with this guy that I have nothing in common with. He’s nice, we just don’t connect at all. He has dreams of becoming a Pentocostal preacher and I’m an atheist. He has made comments to me regarding his wife and just comments in general that make me think he doesn’t have a terribly high opinion of women, which makes me insane. I went in the office and told them I would drive, and I think that made him a little mad, but I don’t care. We will be together from 9am to probably 830pm or 9pm. I really don’t have anything to say to the guy. I can get along with just about anyone, we have a cordial relationship at work, but I’m dreading our 12 hour day together. Any ideas on how I can make this better, other than coming down with H1N1 and not being able to go?
