Great roads in the west!
I had the opportunity to live in Colorado that has many great roads. Loco Denver folks will all know Turkey Creek Canyon Road.
Lyons to Estes Park on Hwy 7 is a good fast drive, but Hwy 66 is the shorter more challenging route with increasing and decreasing radius turns is my favorite. The the canyon from Estes to Ft. Collins on Hwy 34 is pretty awesome too.
I once had to drive to So. Cal from CO and found 89A from Flagstaff headed SW. That was pretty spectacular in February. After all the twisties to flatten out on the desert floor and the Cactus all in bloom.
Wait . . . are there any bad roads in a Teener?
