Time to go, but how?

I've made several 3500 - 4000 mile trips from the west to the east. I think you'll find that once you get west of the Mississippi, and clear of major cities, driving 55 is not a hazard, 60 is absolutely no problem. Traffic is a lot thinner and there are longer sight lines, people can see you a long way off and go around.

This is especially true if you take US highways instead of interstates. Across KY US 68/KY 80 is a great road, connects to US 60 in MO, an excellent 4-lane smooth as glass. Much more scenic than I-40 and very few semi's. US 36 across KS is pretty good, too.
