Get your kicks on Route 66!

Fall on your knees
Oh, hear the angels' voices.

Chestnuts roasting on an open fire
Jack Frost nipping at your toes

And then someday, they may recall
We were not too young at all.

Chestnuts roasting on an open fire
Jack Frost nipping at your nose

Are there any other kinds of reasons why you would love her?

In gereral, I've always liked this song. But in these lines is a case of using a word inaccurately in order to make a rhyme. The whole song generally is about "they" (perhaps the parents of the young lovers) thinking the lovers were too young to know the meaning of love. In these lines, the singer contemplates that maybe someday "they" will finally recognize or acknowledge (for the first time) that the lovers in question really weren't too young. Trouble is, that isn't what "recall" means. "Recall" means to recollect something that one was previously aware of, not to recognize or acknowledge something for the first time.

No doubt the most fabled highway route in U.S. History, U.S. Route 66 stretched from Chicago to Los Angeles. But now U.S. 66 per se no longer exists, nor does any other single route number traverse the same legendary route. To travel the same general corridor on today's modern highways means following Interstate 55 from Chicago to St. Louis, then Interstate 44 from St. Louis to Oklahoma City, then Interstate 40 from there to Barstow, California, then Interstate 15 and/or 215 from there to San Bernardino or Ontario, and finally Interstate 10 from there on to Los Angeles. That combination of routes could scarcely be the basis ot a similarly catchy song!

The state of California, plus Route 66 is also an actual place as a Federal Highway.

The Third verse mentions the states of Missouri, Oklahoma, New Mexico and Arizona and the cities of Saint Louis, MO, Joplin, MO, Oklahoma City, Amarillo, TX, Gallup, NM, Flagstaff, AZ, Winona, AZ, Kingman, AZ, Barstow, CA and San Bernardino, CA.
