Thanks, I also came quite close to h4ck3r, but I knew that one needed a fair bit of time allocating, so I need to plan another trip to do that one, and any other interesting nearby caches, above ground though ;-)
I have emailed phillimore clan who are the holding account for all mad h@ter and another geocachers hides, they own LQ Bristol, so I am hopeful of a reply from them.
Hopefully the cache will get sorted soon, else we may be looking for a replacement cache to be hidden, so it can be anywhere in the county then :-)
