 Okay, and for those of you who have heard that sound before, I'm going to bet it made the hair stand up on the back of your neck because it always does for me. And for those of you who have never heard that sound before, folks, that is the sound of a timber rattler rattling its tail to let others know that it's there, that it's annoyed, it's possibly been startled, and it's a sound that you can hear here in northeastern Pennsylvania.
