I tell you what should work like a champ, but it would be readily visible from a distance, depending on the terrain, and have to be replaced periodically...hay or straw bales.I've thought of it, actually, but never got around to it. I'm sure if I inquired with the high and mighty there'd be flap about it, but nobody cares if nobody asks.It's seasonal---it dries up in late summer, and is big enough for ducks to swim in in spring. Maybe 5' wide, 1' deep?
