I picked Longlac because there's a long stretch of pretty-much-nothing to the east of it until Calstock (Geraldton's to the west). Even if you're driving an ICE vehicle, you want to keep an eye on your gas if you're up that way. You'd need to be even more careful if you were driving an electric on a -36C January morning. Maybe one of the handful of campgrounds or tourist resorts along that stretch has a charger (if they don't, they should get some put in, 'cause they'd probably make a killing).
