This is a Challenge Cache and IS located at the posted coordinates. In order to claim a find you must have met the terms of the challenge. You may sign the log at any time and post a note on the cache page. Any "found it" logs that don't qualify will be deleted. There is a challenge checker you can run to see if you qualify.
Important information: This is on private property and the owners know all about this cache and approved it's location. You do not need to check in when you go to find this.
I enjoy geocaching and camping. There are lots of caches near the campgrounds so if you get out some, and being at this location, I assume you do, you should be able to qualify for this cache. All you need is 10 caches with the camping available attribute.
