Yikes! That is scary! In my old house, the pilot lights were kinda open at the top of the stove, so any air movement would blow them out. I'd always wake up in the middle of the night to that awful smell and we'd have to air out the house. I had such a nose for it that when I moved into this house, I could smell it in the garage. I told the people at work that I hated that smell. They were like, umm, it shouldn't smell. I totally freaked thinking the house was going to blow up. I had the gas company come out right away, and they said they were surprised I could smell it because the leak was so tiny. LOL. I have a nose for it now, that's for sure.
