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?
