The stink

The heat has left our house with the most foul smell that we cannot place. Our guesses- dead thing somewhere, garbage can from hell or mystery diaper. My husbands great idea was to finally take the trash out- but the smell followed and lingered en route. So, he decided to take the trash can out and hose it down. We have a front yard, we have a backyard and we have neighbors. Where does he decide to move the can... the front yard. And it's been out there all day. Do you hear banjos?
