The prizes were donated by the shops around the area. We did quite well. The biggest hurddle we hit was a need for liability insurance that the shopping center required. It was a lot of fun.

How did the prize for "last duck" work"?
What happened if 2 (or more) got stuck & thus never finished (re: crossed finish line)??
Was there a time limit for ducks after a majority of them crossed the finish line for the "last duck" to cross & that one was declared the winner??
I can see something like that (maybe) being an issue if there wasn't a clause written into the rules to say something about those stuck ducks.
Just wondering!
