Reason #654 that people involved with heroin are stupid.  Seeing a "Yard Sale" sign around a neighborhood is a pretty common thing.  Seeing a "Heroin for Sale" flyer that includes an address, well that is not something you see everyday.

Actually the clowns that made the flyer should of included all of the drugs they were selling. When police raided the home, they found more than just heroin. Officers found a sawed off shot gun, weed, thousands of dollars in cash and a meth lab. This was one hell of a garage sale!

King 5 is reporting that a fellow neighbor gave one of the flyers to authorities.  Apparently the house had been under suspicion for about a year.  Neighbors were so happy to see the six adults in the house be placed under arrest, that one woman even made cookies for the officers.
