We attended an evening work event at Sea World over the weekend - when we pulled in the kid manning the parking booth recognized the Leaf and went out of his way to give us turn by turn directions to the cluster of Chargepoint stations in the middle of the sea of parking, and emphasize that charging was free. We were not in desperate need of juice but 3 of the four spaces were vacant (one ICEd by a Corolla) and it was near the end of the regular hours day, so I figured we'd go ahead and take them up on it to show support for the concept. We have a Chargepoint card (not currently linked to a credit card) which activated the unit, though I reckon we could have called someone to activate if we didn't have the card. It fired up right away, unlocked the plug and we were in business. Got topped up while we were at the event. I didn't know I was supposed to end the charge by waving the card again, I just unplugged.
Overall a very pleasant experience, diminished only by seeing a humungous ICE SUV wedging its way into one of the other spaces as we walked away. That really ate away at me until my attention was refocused by the violent motion of the Manta roller coaster a while later.
I was promised a jet pack!
