The lyrics to “By the Time I Get to Phoenix” don’t specify where Glen began his trip to Oklahoma. I assume it was probably Buckeye, Wickenburg, Goodyear or Palo Verde, Ariz. If he had started further north or west, he would have gone through Flagstaff, and if he started further south, he would have gone through Casa Grande.
Yes, the song is not 100% accurate but it is a great song!
