nodrog1964: I am taking this off line as following a site visit it is apparent that while the site was suitable in the winter the area is used by many and various for activities that I do not want to attract children or adults for that matter.
The cache appears to have been discovered and taken from the site I now have some disappointed children but we will try again over the summer.
Thanks to all those who found the cache as it has been fun reading the exploits of those who found the cache. [:D]
