And a tyrannosaurus robot to chew up little bullies. I can hardly wait.

I think this is a great idea. A Brachiosaurus slide would be excellent. Stegosaurus would be good to climb on because of the plates. You could have smaller dinos to ride on instead of the usual horses. A few scary looking ones would make it more exciting, but not too scary of course. Speaking of which, I've always thought that T-rex sculptures would look more dignified and realistic with their mouths closed. They always seem to want to show them bearing their teeth. I think sculptures of lions look more dignified with their mouths closed. It would be the same for T-rex.

I do think this could be fun for kids.

Unfortunatly, I think the reason that this isn't done is because playground equipment is subject to vandalism, so it's usually made of welded steel. Large scale-looking shapes are difficult to make from steel, so fiberglass would be the next choice, but at risk of destruction.

This isn't a new idea. It's already been done. We had stegosaurus monkey bars when I was in elementary school (15 years ago).
