water play with multiple activities. It would be neat to have an area where several short hoses and sprayers with containers could be attached. I'd make it longer so that children would be spaced farther apart but I like the natural look of what appears to be a wooden wall and possible wooden steps or a bench behind it to provide better access from the top.
I would punch babies, launch puppies, key 1970's Chevrolet trucks, light a Gibson Les Paul on fire, and leave original 16th-century scores out in the rain to go to one of these places. Of course, i could just as easy make them into lamp shades like William Randolph Hearst...
