'Last Dollar (Fly Away)'
-- Tim McGraw (2006)

The bottom lines: "I'm down to my last dollar/I've walked right through my shoes/Just a small reminder of the hell that I've gone through."

Kris Kristofferson once wrote, "Freedom's just another word for nothing left to lose." That might be the mantra for McGraw's carefree wanderer (in a song written by Big & Rich's Big Kenny). He lives in the moment, "'cause tomorrow I might have to go and fly away."
