CJ,<br><br>Thanks; interesting read, albeit from a Manhattan viewpoint. We are all downwind from something, though... While I strongly believe that it's worth knowing what to do, I also don't lose any sleep over the prospect.<br><br>Tom<br><br>PS: Here's the link to the article. One must have a (free) account with the NY Times to read the article. I no longer get their daily blurbs in my mail box because my email address changed, but my old ID/PW still work... I suggest using a throw-away emaill address to create an account there.
