Geocaching.com guidelines for difficulty and terrain ratings (found here) state that a T 5 cache
Requires specialized equipment such as scuba gear, a boat, rock climbing gear, or similar.
Hmmmm. By all rights, this should be a T10... or maybe just a T9. Good luck
Please note: Some might consider this cache to be a bit.... dangerous. You are under no obligation to even attempt to find this cache. If you do find the cache, you are obligated to replace it as found!
But... this cache is placed near a couple that were placed In The Beginning.
Stevie would approve.
