Brian,<br><br>I wasn't suggesting that they be depended upon. I only wanted to point out that that they are everywhere, or so it seems, and that they should be considered before breaking out the condom or oven bag or whatever. One man's trash is another man's treasure and all that. I was so acclimatized to seeing them that I never noticed them. It was so obvious that I missed it for years. I wanted to make sure that no one else overlooks the obvious. Reminds me of a Poe short story, "The Purloined Letter." <br><br>Andy
