As a subdivision of Treasure Hunt Adventures, The Great Central Park Treasure Hunt is a do-it-yourself map-based treasure hunt designed for families. You buy a full-color orienteering map to find clues that ultimately spell out a secret message for a treasure you claim online. This is the first of many City-based treasure hunts. In addition to expanding the existing website (did the parent site 9 months ago), I created a few banner ads and this in-site orienteering game.
