Come to think of it, I remember such devices in all the public parks
back home. They have all disappeared. Now I know why. I am sure the
little (and not so little) so and so's could find ways of contaminating
them. The contamination may or may not harm you but it would give them
intense pleasure to think you were drinking the water:-(
