Be very, very careful.
This cache has a long and colorful history.
Part One
I had placed a cache for the 2004 Chicagoland Geocachers Picnic called 'Cook County Cemetery' and after a few groups had entered the grounds of Oak Forest Hospital the security there asked for it to be removed.
Part Two
Nervous Nick and I had placed a cache after the picnic as a memorial and after being reviewed by the cache owner he stated...
"Nobody will climb the tree to get to it. 10 or 15 feet is one thing, but from that height somebody could possibly be killed if they slipped and fell."
Part Three
Needless to say the memorial cache was retrieved and the cache from the Cook County Cemetery (With a new logbook) was put in its place. It eventually got archived.
Fast forward to today...
Part Four
Thinking fondly back on this cache and checking the distance from other caches I decided to bring it back from the dead. Trouble is it had been archived for far too long so a new listing was created.
Be very, very careful.
All who have been up there agreed is very dangerous.
DO NOT ATTEMPT unless you are very good at this sort of thing and/or have the proper equipment to make sure you don't fall.
Make sure it is tethered securely.
If you do fall and get killed please make sure your friends post a picture here with their log. :)
Beta-tester didn't make it. :(
With all of that said, Have Fun!
