Is there a hyphen in the word "Count-down"?

I was recently told there wasn't but that's ok. Who really cares? The more important thing is that we are all counting down to the NFL draft this weekend. With a few extra hours to wait due to the new changes to the format (starts 3pm instead of 12noon), maybe our entire Saturday will not be consumed by draft-watching... hah, who am I kidding? Pre-draft coverage will probably begin at 9am.
