did you know that natural gas is odorless...they actually add "smell" to it so that you know when something is wrong. that's my interesting fact of the day
@aggiebutterfly: Yep. Mercaptans are added to give it that really nasty rotten egg/cabbage smell. The gas companies were forced to do this after the school in northeast Texas blew up because of a gas leak that no one noticed back in the early 1900's.
