You are looking for a Bison Tube, hidden in plain sight. I'd like to think it is cleverly hidden.
If no one catches the hiding spot after a while, I will add a clue at the hide location.
Be mindful of Muggles and please put the cache back as you found it.
The cache has a log only, please bring a pen.
Congratulations to SpiritGuide for the First To Find!!!
