We all dread the bison tube hidden in a tree, especially if it is a green bison tube. Yes, this is a bison tube and it is hanging from a tree. Even so don't go off with any preconceived notions.
Cache is placed with the landowners’ permission. Land is part of the Wisconsin Managed Forest Law Program and is “open” to the public. Open designation allows public access to the property only for hunting, fishing, hiking, sight-seeing and cross-country skiing without additional permission from landowners. The landowners’ grant additional permission to geocachers to search for caches.
