Cache is NOT at posted coordinates.  The posted coordinates are at the Notre Dame Stadium and I doubt you will be able to get there, however that would be a great place to play this cartridge, since you need at least 200' of space to complete it.  Download and complete the Wherigo cartridge to unlock the final.  

This is the Indiana version of a Wherigo project by Rusty O Junk, who is trying to make a Wherigo cartridge for all 50 states.

For this Wherigo, you must start by choosing “Indiana” so you will get the correct final coordinates.  The cartridge is “Play Anywhere” so you can complete it before you make the trip to the area. 

You can download the cartridge here:

Enjoy!
