As I drive the bus past farms every day, I sometimes see the manure pits that the farmers have where they put the cow manure.  I guess they end up selling it or using it down the road for fertilizer.  Anyway, when I see the pits I am reminded of how last July a family from around here died from methane gas when they went into a manure pit.  I don’t understand why anyone would even go INTO a manure pit without a gas mask on!  That methane can kill you in an instant.
