Count me in. The closest I ever got to anything like this was a rusty red rocket in a public park that smelled like urine. I can’t remember the last time I saw a playground of any kind.
EDIT (1/10/12): Lefty Limbo has discovered Rocketship Park in Torrance, California. I’d forgotten about the slide, but the “stages”… My God, what a clusterfuck that was.
