My creek/sewer ranges from 4 inches deep to about a foot and a half. I don't see the ducks much anymore, but I do enjoy the strange array of things I observe on a daily basis. I hope I always live near a creek/sewer/river. The red object in the picture (taken from my cell phone so the quality is poor) is a child's raft of some sort.
Once I saw a guinea pig on a pizza box, floating past my patio. Nearby, a group of children laughed. I of course, having such a sore spot for animals, yelled like a crazy old lady on a New York Balcony.
