Tips for something big....(Driving cross-country)

[Greg Perkins]

Hey you guys,

I've been talking to a few of my friends, and while I'm still young, I want (actually need) to see more of the world and our country. I'm planning to go with some friends to the caribbean next winter, which will be awesome. But that's not my main question, I also want to drive cross country and visit historical landmarks, and national parks. Has anyone ever done this, and what should I expect? Planning is always a big part before I go on trips, so I'd like some thoughts to go on as I'm pretty clueless so far. I plan on having myself, and two(or three) friends accompany me, so splitting driving time is crucial. Any help would be great guys, thanks!
