Day -2: Road trip delayed

 I tested positive for Covid yesterday morning, 3 days before my planned start date for the US road trip.  I am resting and quarantining right now and will decide on a new start date based on my recovery and how I am doing. The symptoms are not too bad right now. It is a bummer to have this happen, but the silver lining is that I got it before starting the trip and not a few days later. My feeling is similar to what astronauts might be going through, if their space mission is delayed a few days before launch.

I need to have recovered and feel well enough to start the road trip. However, I can't wait too many days because that increases the chances of runni

Planning for a long road trip in a Tesla

  Route planning How does one create an optimal driving route that touches all 48 lower states in US, while minimizing the distance covered? This was a problem Dr Randal Olson worked on in 2015 using genetic algorithms: Computing the optimal road trip across the U.S.  In 2016, he also created the Optimal U.S. National Parks road trip . Using these blog posts as the starting point, I investigated the plethora of online resources available for route planning. I had an additional constraint of mapping the route for an electric car, my Tesla Model 3.  Charging locations are still a problem off the beaten track, away from the interstate highways, especially inside some national parks. The resources I found most useful and ended up utilizing for my route plan: A Better Route Planner Recommends supercharger stops for route, how long to stop to charge.
