I'm a big fan of puzzlehunts. The MIT Mystery Hunt is one of the bigger events in a puzzler's calendar, and has been going strong for over 30 years! But the first time I ever got involved in a public treasure hunt was back in 2009 when a guy from Wellington who got dumped by his girlfriend decided to hold a treasure hunt to give the ring away. It was an event that even made international headlines, and being the gamesmaster was something I aspired to do myself.
