The point isn't to arrive in as little time as possible but to enjoy every bit of it along the way. It's a 3,000-mile drive . . . if you go straight across. It's a long journey any way that you look at it, so don't stress about how much distance there is to go or getting from point A to point B. If you see something that looks cool, get out and explore. The adventure will be well worth a couple of hours added to your travel time.
