You can see for miles

A group of English tourists climbing in Snowdonia came across a shepherd sitting at the top of the hill watching over his sheep.

"I suppose you can see a great distance from here on a clear day," said one of the tourists.

"Yes, indeed," said the shepherd seriously, "on a clear day you can see five television regions.

"I suppose on a clear day now you could see as far as London from this great altitude," said one of the climbers, nudging his companions.

"Oh, you can see much farther than that," said the shepherd.

"Further than London?" gasped the tourists.

"Oh, yes, further than America even."

"Further than America?" shouted the climbers, "that's impossible."

"Well," said the shepherd, "if you don't believe me, just you sit down here for a couple of hours and if the clouds will clear you'll see the moon.
