Whose woods these are I think I know.
His house is in the village, though;
He will not see me stopping here
To watch his woods fill up with snow.
My little horse must think it queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year.
He gives his harness bells a shake
To ask if there is some mistake.
The only other sound’s the sweep
Of easy wind and downy flake.
The woods are lovely, dark, and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.
— Robert Frost, 1923
(Not quite evening, but I like to think that this is close to what Frost had in mind.)

What a beautiful photograph of such beautiful trees. It would be so difficult to NOT wander off into those woods. Especially if one didn’t happen to have any ‘promises to keep’ on that particular day.
