This is a bonus cache for my Adventure called "La Crosse Landmarks". To find this you will first need to complete all 5 stages of that. If you want to complete it you will have to use a special app or website. Called "Adventure". My adventure brings you to these locations: Grandad's Bluff, Eagle Watch, International Peace Gardens, Cass Street Bridges, and World's Largest 6-Pack of Beer. After you complete every stage you will see stars and a congratulatory message. In this message, I give you what one letter equals. The final is located at N43 48.7AB W91 12.CDE.
The final is located on the new biking/hiking trails on grand dad's bluff. I would recommend doing that waypoint last. You will be treated to a penut butter jar, and a nice view. Please use stealth, and be safe. As always have fun and good luck.
