Greetings . . . . . I am traveling from Santa Fe, NM to Chapel Hill, NC very soon. I have driven this route before on I-40 and really had concerns about drivers in Tennessee (sorry, the roads were curvy and steep and the drivers were driving dangerously). I am not fond of mountain driving . . . . . do not care for steep grades, switchbacks, curves, etc. I am trying to decide whether to take I-40 from Knoxville through Asheville or to take an alternate route - Johnson City, Elizabethton TN to US Highway 321 through Boone, NC. Has anyone been on 321 before? Are there steep grades and heavy mountain driving? Just wondering which would be a saner choice?? Would appreciate any comments or suggestions! Thanks!
