Have a safe and pleasant drive, Susan! When driving west I always make a point of stopping somewhere at sunset to avoid the glare. You'll notice most of the truckers do the same thing. Sunset = Dinner time, walk around a rest area time, whatever. I always enjoyed travelling with an animal, most of the time I travelled with a cat. They can be great company, especially at that point after sunset when the dome of darkness is advancing across the sky above you, the last light before the stars come out. There's a psychological event if you're out on the road at that time, I'm sure of it. Having the dog will help.
