Well, I really appreciate all of the replies on this. It just reaffirms what
I thought to begin with. Like I said I've heard this before but it was
REALLY loud and scary this morning and I've never experience it with this
bus - espescially concerned me because it only sat over night.

Now that a few of you have explained it - I understand it a bit more. I'll
keep my eye/ear out but I think I'm probably OK.

Again I greatly appreciate the responses.
