Simply Paul: Picked up by bicycle today ahead of fresh caches going out in the area for the local Mega next month. Thanks everyone who found this, and sorry to those who DNF'd it. This one put up a BIG fight, in both directions, as it'd moved a long way. Found it looking at me in the end! Glad I was able to locate it.
SP - Winter Geolympix Mega - GC75FTF - Oct 27th - Ashridge, Herts. The UK's oldest Puzzle cache. England's oldest caches. Stands and stalls. Awesome Night Caching and much more!
