Help! What is the BEST highway anthem out there?

As I drove from Phoenix to Sedona today I indulged in a highway/road trip anthem that I grudgingly confess to having on my iPod: Life is a Highway by Rascal Flatts

Courtesy of: Velma looks just like the babe to the right 😉

So PLEASE tell me what are some other highway anthems? A must have tune that will send us soaring down the interstate? Or inspire us to see all of the U.S.? And that has that good ol’ American feel? Or not?
