I charged at Arlington this afternoon, putting me at 78 unique Superchargers visited.
Note: Please don't turn left from the top of the ramp into the aisle where the Superchargers are. The garage is right turn only, so you have to turn right at the top of the ramp and go through the building overhang to get to the Superchargers. The signage is there, but it's kind of obscured by the surplus Hondas littering the garage.
