This cache will take you back to your childhood where every day was filled with feats of agility and intestinal fortitude. It will take you back to a time where climbing trees was as natural as walking down a sidewalk. If you are afraid of heights you should not attempt this cache. Its difficulty rating is aptly chosen.
However, if you still have that little kid inside, that little voice telling you to climb whenever you see a tree, then bring a smile and a pen because this cache is for you.
You are looking for a baby blood-vial hanging just above an orange metal triangle. You will be able to spot it from the ground, but that doesn't mean retreiving it will be easy.
