I'm off to a John Mayer concert I really want to bring my 85 MS, but I live about 100 miles north of Sac and I have some range anxiety. I'll be getting out of Sacramento late, and don't want to sit at a charger for 2 hours to get 40 miles of charge to get me home. I can't wait for the Supercharger in N. Sac to be completed, that would solve everything, but unfortunately it hasn't even started construction. The concert is at Golden1 Arena, downtown. Does anyone have some advice on what might be available so it can charge while at the concert and we can just head on home after? Like I said, I just need about 40-50 miles of charge to get me home (its hot, and AC will be going full blast there and back!)
