The only thing,
@garneska, is that you don't have to go all the way into Chattanooga to make the i75 turnoff. You come down i75 from Kville by Hamilton Place Mall past the East Brainerd Road exit and turn south onto i75. I have memories (
scars) from 40 years ago of driving this road from Kville to Ttown (and visa versa) about 25-30 times over 4 years. Other than adding lanes via widening, it hasn't stupid changed in those 40 years from Cnooga to West Kville. You don't hit bad traffic in Cnooga on this route. If you went further over Missionary Ridge and into Cnooga proper and around the 2lane TN River curve of i24, then traffic gets hairy.
Save those two hours for Atlanta. Lived there for 3 years in the 90s. Glad I don't no more. Traffic hasn't gotten better.
I'll toss it back to you, Kris!
