Answer: STOPPING BY WOODS ON A SNOWY EVENING
Problem: Christmas Town/​Halloween Town

This puzzle consists of 13 license plates from 13 different U.S. states (presented in alphabetical order by state), each with a slogan and a license plate number.

The letters of the plate are the initials of a poet who was born in the given state. The corresponding slogan is a phrase found in one of that poet’s works. The three numbers index into the quoted poem, as indicated by the first three lines of the flavortext:

The line to see Santa’s so long. What a wait!
(The word has gone out that he’s jolly and kind.)
The letters he gets come from state after state,
And the traffic’s unlike any other you’d find.

For example, on the Massachusetts plate the letters EAP indicate Edgar Allan Poe, the slogan “Kingdom by the Sea” is a phrase from Poe’s poem “Annabel Lee” and the number 183 indicates the first line, eighth word, third letter:

It was many and many a year ago

which gives us the letter O.

The states chosen can be linked in a continuous line from west to east, giving an ordering of the extracted letters. In that order, the authors, poems, lines and extracted letters are:
