Let us proffer a warning to you: Watch where you step in this outdoor polymorphic and polychromed playground. There are broken beer bottles, discharged spray cans, rusty rebar, and hard-edged, concrete lining sinkholes. Safety first, people. But we suggest watching your step for another reason, namely that the nature of the art here is ephemeral, and if you're not looking everywhere (up and down), you may miss some mark or message in one of the many concrete wells. Take in the view, sure, but live in the minutiae.
