There's lots of fences in the Lake District, with steps on both sides so strollers can climb over but the sheep can't. Common sight I suppose for an Englishman, but as an American, I was impressed. There's lots of rocks too, all the way up to what the English call mountains. Ambleside and other small towns on the edge of Lake Windemere are built on the side of hills, with very narrow streets. You walk into a building off the street and go to the back of the building and look down and you see that you're on the second or third storey from the other side. Buildings on the other side of the street aren't very deep. Hills and mountains in the way.
