Just as you can slice a pie in a million different ways, you can consider as many interpretations of this poem as you like. In fact, this poem demands that you look at it from multiple angles. That's the beauty of Frost. But don't let the limitless possibilities trip you up. This happens to be one of the most beloved, oft recited, oft quoted, oft referenced poems in America (yes, we just use the word "oft" three times), and it doesn't mind at all if you choose not to go digging for underlying meaning. You have free rein to enjoy the beautiful snow and the peaceful quiet.
