We make this trip 2-3 times a year. Looking at the PlugShare maps is depressing. Nothing near Pendelton but a wall outlet? I would LOVE to be able to make this trip in a day (approx. 430 miles), but that would only be possible with Supercharging. I'm resigned to a 2 day affair. The way the charge stations seem to be spread out, I'm worried that even the 2 day trip may be pushing it. Nothing on the map between The Dalles and Boise. I'm shocked there aren't more charging options on the way out there. I know there a couple Boise Model S reservations. I wonder if anyone else has thought about this drive?
