If you are planning on driving around for Trick or Treating or if you are just going to be at home handing out candy on Tuesday, turn on WILL-FM to listen to spooky music. Tune to 101.1 in Champaign, 106.5 in Danville, and 90.9 if you are farther out. From 5-8pm on Halloween (this Tuesday) they will have a wonderful Halloween soundtrack for you to enjoy.
I've listened in the past and heard songs I recognize from movies---the Omen, Vertigo, and more. It's fantastic and *really* puts you in the mood for Halloween.
