The most nerve racking thing about being the dropper was casing the location to make sure no one was already there.
I did the War Memorial one year, the Art Museum grounds another, and a Larry Bird statue the final year.
Art Museum grounds was probably the funnest one. First, it was a great pic I took of the helmet. But to see all those minivans come screeching into the museum parking lot was hilarious. Sure there were some art lovers completely dumbfounded at what new exhibit must be drawing the crowd.
