Where in the world?

I always thought my dream setting, not just for writing, but for life in general, would be a cabin in the mountains on a lake.  Water and mountains were the key ingredient.  I saw this place once.  It was  in a painting by Maxfield Parrish called "House at the End of the World."  But over the years I've come to realize (mostly due to financial challenges) that the setting isn't important for getting the work done, it's the solitude.

Describe your dream writing setting: cabin in the woods, house on the beach, up in the mountains, down in the valley?
