Re: At Vince H, re: FlockChain...
Ah, but the thing is... it's true.
I can even identify the exact date by glancing back through my pictures (none of the sheep - just by finding the the right set of photos, including those from where it happened): 9th April, 2007 - Fice's Well on Dartmoor.
I'm just glad I hadn't watched the documentary Black Sheep (2006), the night before.
