This lovely writer / historian Alexis Coe who I met through Elizabeth has a podcast that you need for your commute: Presidents are People, too. It has friendly, accessible 25 min episodes, each devoted to little known facts about a US president. You need it. You will arrive at your destination slightly more informed, slightly more Patriotic, and even mildly less annoyed by the fact that WHY DO I HAVE TO LIVE IN A PLACE WHERE ALSO TEN BILLION PEOPLE ALSO LIVE AND EACH OF THEM APPEAR TO HAVE NINE CARS AND WE ALL SEEM TO BE GOING TO THE SAME PLACE.
