> My advice to anybody that wants to do stuff like this: just do it. Take a day or two off next to a weekend, load up the car with food, blankets, and every comfort or amenity imaginable, and just drive.

I like this perspective on it. I'd like to try it, but I run into the same thing as some others have mentioned: I'd rather not do it alone. I'm sure I can resolve that problem with a little effort, though. :-)
