Do you ever just put the car radio on SCAN?
I've been doing a far amount of traveling recently - in addition to the move from Massachusetts at the end of November I also made a trip up and back over this past weekend.
So I've had lots of radio time while I travel... yeah I did have a few CD's with me but even those get old after a while.
It's especially interesting if you are in an area that has lots of stations with a wide variety of formats. It's been fun to listen as one 5 second sampling leads to the next... you never know what to expect and it's kinda funny sometimes.
So go ahead and hit your scan button and sit back and enjoy!
