10 When we bought the house … It had a little creek in back The kids like to play back there We fed the geese We dumped our grass clippings That’s where I get rid of brush  Now it’s a thicket  The banks are eroding  The geese are everywhere. They make such a mess  What does it hurt to throw grass and branches in the creek?
