Overall, no floats just yet. However there are fog boxes, garland and streamers to help with the Mardis Gras feel.

Central park seemed a little over half finished with the pumpkins, with the majority of the ground stuff done. I did not see a Storyteller pumpkin, although I may have missed it given the crummy weather situation.

I would assume this will be finished after Rock the Universe, with some minor stuff going up beforehand.
