Ah, not that old chestnut I hear you say. Yep, it is, but come and have a go anyway. It's a bit of fun.
Another cache where all you have to do is go to GZ, find the cache, grab the log, and sign it. What could be easier!! 
Now, I need you to be a little careful with this one and not push anything back into place too hard.....and if you need any extra 'filling' there is a pile behind the tree, about 4 metres uphill from GZ. Sort of a built in maintenance application.....just in case.
I don't think the cache will be seen by anyone walking along the nearby fire trail, but PLEASE ensure you replace the camo before leaving. If everyone can replace things just as you find them.......all will be fine.
Enjoy.....and read the last sentence on the first line again........
