On a similar note, I have to admit to having gone to Casterton Circle 3 times and I still haven't seen the bugger!
Even following Jane's "easy" instructions last time, I still missed it. By the time I'd counted 5 field boundaries, we were at the top of the hill, over-looking moorland and my legs were aching like bugger! It isn't on my OS map either, which doesn't help.
C'mon Jane (Or Moth) - help me out!
