What does the song fast by Jason Aldean mean?

Answer 1

Jason sings about losing the way of life he once knew and losing his farm. He sings "Aren't those four lanes fast." It could be that he is talking about an interstate being paved through his farm/town and losing the way of life that he once knew and loved.

The four lanes could also symbolize the four years of highschool or college and growing up and moving on in life. A bitter sweet time.

It could also be a song for growing up in general and moving on.
