GPS Adventures “is a hands-on traveling exhibit that features GPS technology — its history, current uses and future possibilities; and simulates geocaching indoors by leading visitors through a 2,500 square foot maze rich with interactive experiences.” At Minnetrista, an Indiana cultural centre and museum, from June 2 until September 3. Geocachers are calling the opening an “event cache,” which is their funny way of describing a meeting. Via Gadling.
