I am down in Pagosa, my Model S is in Boulder after some fun track time before shoeing it with its winter tires. Now its time to get the Model S here to its permanent home. Because of schedules, it is working out best for my friend drive my Model S down here today and fly back with me tomorrow. He is a flight instructor that I trust with my airplane (worth more that the Sig Model S), and pretty good with vehicles in general, but not up to speed on electric road tripping. This is not an easy drive, its 295 miles, 3,000 ft net up hill, goes over 4 passes, and usually has head winds. The charge recommendations that I gave him were conservative to avoid any chance of range anxiety. I sent him a detailed e-mail that he recommended that I publish. Here are those instructions for others to share and comment.
