This cache might just have you screaming AHHHHHH Nuts!

In an attempt to create more challenging caches in the area, I have placed this traditional cache with a catch...it is locked.  You must figure out how to retrieve the key from the attached puzzle before you can log this as found.      Simply remove the nuts from the bolt and it will slide apart, but don't think this is a park and grab as you will probably be here for a while.  Bring plenty of water and please reassemble puzzle and reattach the chain exactly as you found it!   

Please don't drive straight to the cache, pull off of main road onto gravel road and then walk the rest!!
