I am planning a summer vacation for my family to North Carolina. We would like to spend some time in the GSMNP area, Ashville, Durham and ultimately the Outer Banks. Flying to/from looks to be a bit complicated so I am considering turning this into a road trip since we will already be doing a fair amount of driving within North Carolina anyway. I would appreciate any tips on best routes and stopping points from Chicago to Ashville/GSMNP and then for the return from the Outer Banks. We will have approximately 8 days for the trip. Thanks!
