Couple of years ago Sarah and I went.....as we say it here in the south...”Creek Stomping “ in middle Tennessee, and we found a piece of driftwood so we brought it back home and I thought the water fall would be a good place for it.....last year it had a little moss on it, but this year plain old Moss likes pond water...... so it goes to show you.....try different things, they won’t all turn out..... but sometimes it’s pretty kool
