Last time I went to Logan airport in Boston they had charging stations for electric cars with parking spots right next to the elevator in the parking garage. There were about 6 spots all empty. Each one had a sign: parking for electric vehicle only. The rest of the garage was full.
What an opportunity: Park a 1959 Cadillac in one of those spots, then run an extension cord (connected to nothing) from under the hood into one of those charging thingies.
