Well here I go again. On Thanksgiving we were at my parents house and it was cold. My wife wanted to take a smoke (my parents don't smoke) outside but it was cold. My dad told her she could smoke in the shop where there was heat. We walked in and I remembered the shop was heated with a propane bottle. At that point I started having trouble breathing, started sweating, yatta, yatta...... I told her it wasn't safe and not to go in. She told me something like nonsense and come in. I turned and walked out into the woods with a book and stayed there. Sometimes this fear (Propane) seems like it was a TV show I saw or a book I read. For a while 10yrs or so If I was driving and saw a propane truck I would stop or go as fast as I could to get around it. Did it in the squad car too. If I remember right a 5 gal. bottle of propane in an explosion expands 622 cubic feet. Big blast. I don't know the metric figure. I can't find anything about how to start or outline the diary. Did I miss it somewhere ?
