Andrew's String Search form

Search for a word or phrase in the poem

The Poem:

Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;

Please enter a word or phrase to search.
