I worked with one of my Closer producers last week and he told me a story about carbon monoxide poisoning.
Two of his friends, who who recently became engaged, decided to take a trip together. (Las Vegas, or some other touristy destination?) They stayed at a Mariott. Their room had a carbon monoxide leak, but they didn't notice anything because they'd had a few drinks and came back to their room and quickly passed out. They woke up a few times and felt kind of dazed and confused but blamed it on the alcohol.
The next morning, room service discovered them and thought they had OD'd on drugs and called 911. Everyone assumed that was what it was but they were able to finally being them back to conciousness. They almost died! And they will be suffering the ramifications for years. I'm sure there will be a lawsuit involved. This was the only room that had the leak!
So needless to say, I'm VERY glad that you have the detector, Elmore! That's something you don't want to mess around with!
