I'm not actually going to be able to go on a road trip this summer, but I'm writing a novel and my characters are! They're going to start out in Durham, North Carolina and end up in Newport, Oregon, taking a pretty twisted route along the way (going through South Carolina, Georgia, Tennessee, Kentucky, Indiana, Illinois, Iowa, Nebraska, Colorado, Utah, and Nevada). Not the most direct route I know, but they're teenagers and they want to see most of the United States.
So my question - or, questions - are - what should they do along this route? What places do they have to see? How much money should they bring? How long should this take them? What essentials do they need in the car (a Ford Explorer)? Also, what would be something interesting that could happen to them along the way?
Thank you! :]
