Once you hit Denver, keep on going west on Hwy 70.
Colors in the mountains will be going off! Aspen, Vail, Leadville, Telluride, etc....
Keep going to Grand Junction and head south to the Four Corners, monument valley area.
Then head east.
You are in for a treat!
Good choices - Vail pass on I-70 is pretty cool. Your 210 horsepower V-6 will start acting like a 50 hp tractor engine as you approach 11,000 feet above sea level. But it's very, very scenic. Make sure you plan some stops in those areas.
Keep going West to Moab, UT and spend a day or two there if you can. Rent a Jeep or other 4WD and explore a bit on the milder and more scenic trails (travel in groups when trailing - stuff happens frequently out there). Arches National park is near Moab, and is beautiful. The rocky Buttes are incredibly colorful in that area with their various layers of red, brown, and orange. I was there in 2000, and all I had to shoot with was an Olympus point-and-shoot 35 mm. But I still managed to fire off some nice shots.
At the east end of the country, Chattanooga and areas nearby are very scenic (and you might get a free lunch from yours truly if you pass through and I'm not working or out of town). There's a lot of Civil War history in this part of the country, with some pivotal battles having taken place close by. The city also has some very nice scenic parks and such. Downtown is pretty clean as well, though it is lacking the huge skyscrapers you'll find in Atlanta, or DC.
Get up into the Appalacians and enjoy a totally different kind of mountain scenery. I'd recommend the Gatlinburg area, but it's incredibly crowded. You might get a cabin up there for a decent price that time of year, and the cabins I've been in were all quite nice. The Ocoee area is particularly scenic, and if you have a penchant for white-water rafting, the Ocoee river offers that (check times and dates as the river is controlled by dams, with consideration to many factors including rafting, flooding, and draught).
If you like hiking, the Appalacian mountians have plenty of trails. Look at some hiking web sites to see what might be available in the various areas. October is very comfortable around here, though it can get rather cool as you head north, especially at night.
