Air travel is down, but I've been reading that road trips to at least some of our National Parks have hit numbers we usually only see during summer. I sat down recently with a man who has a particular passion for the road. He's an author, Matthew Iribarne, whose first work of fiction, "Astronauts and Other Stories", centers on road trips that unfold into personal odysseys. As Matthew puts it, the very nature of being confined in a car pushes us to learn more about ourselves as well as our fellow travelers.
