The Woods and Snow

It's been snowing every day here for a week. Yesterday I had the chance to go for a walk in the woods. It was really quiet in there with the light and fluffy snow falling. It was also very beautiful. It reminded me of this old poem I remembered reading as a school girl. I knew it was probably a Robert Frost poem... and so I went to search for it via the google. Here it is;

Stopping by Woods on a Snowy Evening

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

And isn't that a mention of the winter equinox in this poem?
