Hi, I'm Dave's producer. In just about 3 days we will embark on this crazy trip. I'm excited, and a little scared to be honest. What will happen? Where will we end up?

At least it will be an adventure along the way. Look here for more updates, behind the scene photos and videos from Dave's production team. We will be following him along the way - don't worry, we won't help him. We're counting on America to do that.

We will be updating frequently... from whatever city we are in.
