Hi, I'm planning on driving from Los Angeles to Washington D.C. in July, but I don't have much figured out beyond that. My rough idea is to go to Las Vegas, then Denver, then Chicago, then Detroit and then D.C (with two or three drivers). I'd like to do it in less than a week, but still take some time to see a few sites along the way - is that crazy? National parks, giant balls of twine, good pancakes, stuff like that. Any suggestions on routes or timing or really any advice... Thanks!
