As mentioned before, there is lots to see near Grants, NM. Blue Water State Park has a nice campground on a bluff above the lake. If you have never been to Santa Fe its a quick jog north of Albuquerque and one of my favorites. That stretch from central NM thu Texas, Oklahoma and Arkansas is long haul and I'm guilty of just pounding down the road to get thru it as fast as I can. Hope others have some good ideas for you. Chattanooga has lots of interesting stuff to do and see. Just google the city and you will see a big list of historical and civil war stuff. From Franklin I would highly recommend the Great Smokies and a drive on the Blue Ridge Pkwy.
