Hi Jeff,
Nice to see the grass progressing, the fell is getting a lot more definition now it's not just a single colour. I like the idea of a sheepfold on the fell, but the one you pictured is quite big, which is fairly typical of ones you see in valleys. Up on the tops they tend to be smaller as they are intended for the sheep to shelter in when the weather gets interesting. Down in the valleys the profusion of walls would give them plenty of scope for finding shelter, high up on the open fells, there are few walls, and generally little natural shelter for them. Of course, these days the sheep are hard pressed to fit in them as they all tend to be full of walkers enjoying their lunches (and when the walker is only wearing a mankini, they wouldn't want to be near anyway!).
Oh, and I agree, Spot is a silly name for a sheep. It is of course a name for a zebra.
I'll get me coat...
