What exactly is the "Mystery at the Museum" game-within-the-geocaching-game? I'm not completely sure, but it runs from July 11-Aug 11 and is an opportunity to earn up to 4 new souvenirs. Additional info here.
This quick event will be held in the park just behind the East Library from 12:15-12:45 on Monday July 15th.
