INDIANA — Indiana state park visitors can play the Centennial Geocache Challenge for a chance to win prizes including a 2017 annual entrance permit. The Geocache Challenge is a self-guided activity designed to commemorate the 100th anniversary of Indiana state parks. The Centennial Geocache Passport, downloadable at instateparks100.com, resembles a bingo card with park names in each square. When geocachers locate a Centennial Cache, they stamp the square for the corresponding park. Participants who complete five parks in a row are eligible for prizes, including a 2017 park pass, a $50 camping gift card and a $25 gift card to Cabela’s.
