By the Time I Get to Phoenix- Glen Campbell

In the song, Glen doesn't mention where his trip to Oklahoma by way of Phoenix started. I assume that he departed from Goodyear or Buckeye, Ariz. Had he departed from farther south, he would have gone through Casa Grande, and had he departed from farther west, he would have gone through Flagstaff.
If he started early enough, driving on 1967 highways, he just might have made it to the Oklahoma state line at Texhoma or Texola by nightfall.
