The gates over the openings were barred by not locked, so we figured it meant we could crawl inside. Still, they were carefully recreated on the historic sites and the interior supports are meant to maintain the crumbling state they are in. They are not fake, just artistically maintained, I think. Some things haven't changed much. Lots of 'sheep in the road' up here.
Sheep are stupid.
They just stand there and you have to wait them out since you're not supposed to honk or otherwise scare the lambs. How something as cute as a lamb can grow up to be as stupid and smelly as a sheep is beyond me. A few times you see a lamb 20' from all the other sheep and it's mom. It's the most pathetic thing you've ever heard. I'm sooooo looooooooost.
