I picked up the details needed from Challenge 6 yesterday and eventually cracked the puzzle (it's a stinker, but very rewarding when you do solve it) so I decided on a dawn raid on the cache today.
Parked at the recommended place and had a lovely walk in the fog over to the cache - really tranquil as there was not a soul around. Soon I was at the cache area and found the cache in the first place I looked after my cacher's eye spotted something not quite right.
Definitely the best of the series (the other ones were really good too) - such a lovely location. Only a pity it was so foggy this morning otherwise I'd have seen more of it.
Thanks for the excellent, well thought out series Elis - some great first cache hides here. Hope to see many more new caches from you in the future.
