The river Dee.

"There dwelt a miller, hale and bold, beside the river Dee;
He danced and sang from morn till night, no lark so blithe as he;
And this the burden of his song forever used to be: -
"I care for nobody, no not I, if nobody cares for me."

One of the objectives of the trip was a wander around Bodnant Gardens. Obviously good weather would be a good idea.
It wasn't, so we didn't - today.
Instead we had a bit of a trawl around LLangollen.
("I'll never understand why most Brits turn the Welsh LL nearest pronunciation = "Thl" as in Thlanfairwotsisname
into "Cl" and say Clanfairwotsisname)

By a weird chance, we parked not a million miles from a location by name of "The corn mill", which brought the song to mind.
