I see some old (2015-2018) posts about a few spots allegedly coming but, per Tesla's SuperCharger map just now, I see zero in inner Idaho, only around the state rim. Makes it basically impossible to drive north-south via e.g. Cascade and Grangeville, let alone stay there for a holiday, or the larger and/or university locations of Lewiston and Moscow. And that's with a M3LR. No indications of anything being added in 2019. Maybe 2020? Fingers crossed before my next road trip through there!
