Also: the bit about the shitting cows made me laugh. I'm wondering if the lawns are fenced-in. All the cows I came across were very curious creatures who followed you around or stared at you while standing in the middle of the road. But maybe the Scottish cattle (E.B.'s cattle to be precise) are really just content with being picturesque. ;)
I've already spent too much time thinking about imaginary sheep and cows on imaginary lawns in Scotland. One last question: where do the animals get water? A little undescribed stream next to the castle? Water trough?
