I had no tv on ( as I refuse to get digital) unplugged radio, and put ear plugs in. I know that sounds a bit over the top but I wasn't taking any chances with this. And I also believe the 'test' turned out exactly the way they wanted it to. They planned this out for a long time for it to fail on them. I think the old way to warn us was much more efficient in alerting people...this test was done for other reasons. JMO
