I drive The Bay to Truckee almost every weekend - and the last supercharger before Truckee is at Rocklin (5miles past Roseville) at the service center. I used to have a Bolt and used the EVGo Drive the Arc Charger in Auburn. It takes close to 2 miles of charge per mile covered to get up to Truckee from Rocklin (you are climbing 7300 feet in 80 miles). If the road is iffy with weather it feels a bit intimidating especially know there are 3 more or so EVGo chargers on the hill I could grab with my Bolt if the weather and traffic is horrible, but useless for our X and 3. They also have both Chademo and CCS Fast DC so either adapter would work. I definitely want one of those adapters - prefer CCS but I would grab either.
