Hey Merrick,
They're about seven miles from my house. They are great to see - but you're not garuanteed a sighting if you visit.

There are some "recently added" white cattle in the castle grounds too, they are usually easy to see from the road, but they aren't from the same stock as the wild ones as far as I know.

Haven't been to see them for a few years, must get back there soon
