Highway rest stops are unique places.
Highway rest stops are not a destination. Nobody sets out to go picnic at a rest stop.
Highway rest stops are a stopping point. A harbor, a wayside on the road.They are a place to rest.
You are not required to buy anything to use the bathroom. You can stay as long as you like. Take a nap, walk the dog, stretch your legs.
The cars on the highway are whizzing by just a hundred feet away. But here it is calm. Things are slow. You move at a more natural pace.
Yes, you still have a ways to go, but, for now, you rest.
