Looking for some advice on the best way through NC to Lake Norman. Google shows I 64 S through West Virgina to I 77 S as the best option. But there is another option for 75 to 40 through Tennessee. We will be coming from Illinois. Never been to that part of the country, so I was curious if one was truly better and safer than the other in regard to traveling through the mtns. (Especially at this time of the year) Any thoughts from those that know would be much appreciated. Thanks!
