They trialled the idea on Dartmoor ponies about 2 years ago. It's a broad stripe along the animal's flank which glows in the dark. You can see photos of them if you Google it.

I think it's a good idea, as motorists come across the ponies suddenly in the pitch dark and there are several sad accidents each year. Now they're using it for New Forest ponies.

Venison is ridiculously expensive. I saw some in a butcher's here in Norfolk and it was dearer than fillet steak. And many people don't know how to cook it.
