Looks like I've got 3 main options:
1) North towards Pittsburgh to I80, I90
2) West on 64 and then cut up on hwy 35 towards Dayton.
3) Stay on 64 towards Lexington and not head north until Louisville.
Pros/Cons of each? I seem to remember miserable stretches of 80/90 in past. I've done that hwy 35 before and it's ok but not great. Do the extra mountains you hit on 64 towards Lexington slow you down?
