Some people don’t like scavenger hunts such as geocaching and the old fashioned clues and X marks the spot map because participants sometimes ignore common sense or courtesy. Some of the problems are caused by poor planning on the part of organizers. What was Cadbury Schweppes thinking when they organized a scavenger hunt that included one of the U.S.’s most historic cemeteries? Are people searching for a hidden coin that promises big money prizes going to stop mid-hunt to ponder the graves of John Hancock or Paul Revere? The Boston Parks commission closed the cemetery out of fear that graves would be desecrated. You would like to think that people would know that the coin wouldn’t be buried in a grave, which is probably what the company hired by Cadbury Schweppes was thinking.
