Maybe I should check to see if some company would like to put a "for pay" charger in front of my house!

I saw the chargers in King of Prussia last night. They are between Nordstrom and Sears on the top deck of the parking garage. They're pretty small -- looks like a 2 1/2" black PVC pipe with an electronic box on the top.
The one by the Wayne train station was about 6-9" square, so it was a bit more substantial. It's actually run by Community Energy, so at least your money is going toward producing more wind power in Pennsylvania.
