Wayne--
You'll note that I didn't say it was something I planned to use them for, just that it was a possible use! I agree with you 200%. Around here, I can't envision a possibility where we'd need to evacuate to such a shelter. There's enough family & friends scattered about to preclude the need.
However, I know my wife has used plugs 'cause of my snoring on a few occasions. <img src="images/graemlins/blush.gif" alt="" />
