Do you have a good suggestion on a stop between Oklahoma City and Amarillo? Little Rock to OKC is only 350 miles, and I know he's going to want to cover more ground than that. Or maybe he should just stop in Memphis (or just a bit beyond) the first night and go on from there. If he gets a late start, I think MEM is about as far as he should go. I was trying to break it up in 500 mile incriments just to make it easier. There's nothing worse than a tired driver. They lose alertness and can get careless. He has the time, and he should use it. There's no use in pushing himself.
When you go, where do you stop? And thanks for answering.
