I agree with Karen. I-65 from Louisville to Indy is the worst road I have ever been on in my lifetime. Potholes every 20 feet and you can't dodge them. Bad pavement joints. Places where the concrete is totally popped out leaving foot deep holes. Truck traffic like you wouldn't believe. That road should be illegal. We drove it in August and took it at 55 mph, but even that wasn't slow enough to avoid jarring the heck out of everything.
