Someday lyrics

There ain't a lot that you can do in this town
You drive down to the lake and then you turn back around
You go to school and you learn to read and write
So you can walk into the county bank and sign away your life
[ Lyrics from: http://www.lyricsmode.com/lyrics/s/steve_earle/someday.html ]
I work at the fillin' station on the interstate
Pumpin' gasoline and countin' out of state plates
They ask me how far into Memphis son, and where's the nearest beer
And they don't even know that there's a town around here

Someday I'm finally gonna let go
'Cause I know there's a better way
And I wanna know what's over that rainbow
I'm gonna get out of here someday

Now my brother went to college cause he played football
I'm still hangin' round cause I'm a little bit small
I got me a 67 Chevy, she's low and sleek and black
Someday I'll put her on that interstate and never look back
