Driving into the light

The next six weeks are interesting driving into Charlottesville from the west on I-64.
Four miles west of town, the interstate rises up Ivy Mountain. This time of year, just before 8 a.m., the sun rises in the view of oncoming traffic. One minute you're going 65, then you hit the sunny area and it's a quick slowdown as you're looking pretty much into the sun.
I've found driving behind 18-wheelers helps block the sun. You creep up the hill behind them, but they take the sun. As long as nobody behind you comes up too fast.
Cloudy days are appreciated on the way to work. So is late January, when the sun moves north in the sky and higher when I and my fellow commuters hit the area.
