From Dartmoor

The dogs here are friendly, at least I haven't heard anything howling over the moors. The cows, on the other hand, now those you have to watch.

The picture, from the top of Hayter Tor shows a "tramway" from the old quarries. It doesn't look like much, but it's about 3km of carved stone rails. None of that simple and cheap wood stuff. Imagine the amount of labor that went into it.

Clearly it's better than trying to push carts across muck, but surely there must have been an easier way.
