I would fly. Hope seat away from people and use PPE. My concern with driving is each state is doing their own thing with exposure and risk. I'd rather be 5-6 hr on plane, know the airline requires passengers PPE (and you clean plane, seat around you, etc.), get off and shower immediately, vs. stopping in backwood places/road stops whereas folks are coughing, sneezing, unclean surfaces and cheap off-the-road hotels, etc. Additionally, if the flight is direct you leave a state that cares to a state that cares about its residence. The middle states are more about freedoms/economy and don't care about residents so I'd rather avoid the risk of car break down or other weather forcing me to stay someplace I'd rather not be enroute.
