You will need to complete the nearby Adventure Lab called LaGrange- We're Right on Track in order to solve this puzzle. Completing each stage of the five stage lab will give you an answer to solve for these coordinates:
N 38° 24.ABC W 85° 22.DE0
Parking is nearby for this bonus cache or you can easily walk to it from completing the Adventure Lab! The Lab is not in sequential order but you may want to start at the train museum first and take a lovely walk down Main Street. There are a handful of other fun caches in downtown as well! We hope you enjoyed your visit to LaGrange!
