“By the Time I Get to Phoenix”, “Wichita Lineman” and “Galveston” were all Jimmy Webb songs.
If there are any aspiring songwriters out there, get and read the book “Tunesmith” by Webb.
“By the Time I Get to Phoenix” doesn’t mention the point of origin of the sojourn described in the song. I figure it’s probably Sonoyta, Sonora, or Los Algodones, BC, Mexico.
