I've done work with Make-A-Wish through the 501st before, and the people there will serious stop at nothing to make sure the wishes are fulfilled. This is absolutely incredible.
I heard about this on the radio! It's amazing when you think of all the volunteers and the co-operation from the city (probably) that lined up to make this happen.
Makes me smile :)
