That drive on the 40 between Fort Smith and Little Rock, along the Arkansas River, is some of the most beautiful countryside I have seen on three separate cross-country drives.
My folks bought property in Arkansas years ago when they were planning on retiring from the Chicago area. In the end it came down to a coin toss between Arkansas and eastern Tennessee. Tennessee (south of Knoxville) won out, but Arkansas was for them a very close second.
The crazy thing about the east is how distances compress. Took us two days to drive from the OC to just past Fort Smith. The last day we drove through Little Rock, Memphis, Nashville, Knoxville and Asheville... and stopped just outside of Charlotte
That's a sneaky way of saying - you'll only be one day away!!
