Those who drive long stretches of most US Interstate highways know that, while you’ll get there faster and there might be some good places to pull off, it will be a mostly boring trip.
Fast, efficient, but boring.
If you decide to jump off on a backroad (see William Least Heat-Moon’s Blue Highways) for at least part of the journey, it might add time and you might not see anything, either.
But the chances are good that you WILL make some sort of discovery, the kind that leaves everyone in the car grinning with delight (well, except your teenagers, but they’ll smile inwardly and appreciate it later. You know; years from now.)
That’s what I did driving from Beaumont, Texas back to my home in the Austin area after my high school reunion festivities; I pulled out the map and said, “Please, let there be some road that goes roughly in the correct direction but is not Interstate 10.”
