In Houston area, my wife heard another test of the Emergency Broadcast System early this morning.

She commented that this was the 3rd test of the EBS she's heard in the last 24-hours. She asked me how many tests do they need?

I mentioned that you only get ONE chance to re-take a country and save it from destruction... so you do as many tests as you need to get it right. If SHTF in a month or so, they want as few civilians in the way as possible.
