I've seen this song done in the key of F, but I figure why do it the hard way.
This is my way. 
 
 
G                      C              D7             G
 Rain dripping off the brim of my hat sure is cold today
                      C         D7                           G 
Here I am walkin down Sixty Six wish she hadn't done me that way
                            C               D7                G 
Sleeping under a table in a roadside park a man could wake up dead
                         C           D7                        G 
But it sure seems warmer than it did sleeping in our king size bed 
 
(CHORUS) 
G                  C             D7         G
Is anybody goin to San Antone or Phoenix Arizona
                          C                D7            G 
Any placi is all right as long as I can forget I've ever known her. 
 
 
(Verse 2 same chords as 1) 
Wind whippin down the neck of my shirt like I aint got nothin on 
But I'd rather fight the wind and rain than what I've been fightin at home 
Yonder comes a truck with the U.S. mail people writin letters back home 
Tommorrow she'll probably want me back but I'll still be just as gone 
 
 
(Repeat Chorus)
