This is definately a Tree Fishing cache and not a climbing one. I use to play in this park as a kid as my grandparents lived nearby. It has changed, the council is not mowing the grass low anymore. A cost cutting measure and a way of increasing the insect and bird life.
Please do not retrive the cache if you can not replace it. I have employed a guard to watch the cache.
I am prepared to lend equipment but not for FTF. ( It might cost you a coffee).
