On the 7 trips to CP last year, I only recall seeing one county sheriff on Route 6 and he was going west. I blew past him at 80 mph and he kept on going his own way. That road is pretty much deserted.. I think it's safe to say you can put the pedal to the metal.
But I highly suggest stopping in Findlay to use the restroom and get food if you need it, no matter if you need to or not.
The next station, save for lonely and somewhat shady truck stops, is about 30 miles west of Sandusky. I made the mistake of not stopping in Findlay to use the restroom.. miles and miles later on Route 6 I was dancing in my seat, highly considering just jumping out and using the ditch.
I hit 100 MPH on that road in my own car. I tried to do it in my new one but it would only go about 90mph
