Not just another scavenger hunt!
Have you ever been on a scavenger hunt? As kids, we did this once in a while as a "group activity" when we'd all have to work together to find all the items on a list. We'd make our way through the neighborhood asking the neighbors if they had a blue button, yellow tissue paper, one sock with a hole in it, etc. As our bags filled up we'd become more and more excited because we planned to be the ones to finish our hunt the first, returning back to "home base" with the "loot" of our hunt and being declared the winners. There was always that one item on the list which no one had! It was something absolutely weird and almost impossible to find. It was like we had to go to exactly the right house to find it, but who knew exactly where that was. It could have been a broken Timex watch, or a cooking pot with a hole in the bottom. They weren't things people would keep around because once it was declared to be "not useful" anymore
