The long- awaited, much discussed, occasionally trespassed City Museum roof helped visitors reach new heights for the first time on June 6, 2009. The now-open rooftop features Big Eli, a restored, revived, and revolving four-story Ferris wheel, a wide-and steep rope ramp slide, a stepping stone-festooned Splash Pond, a massive rope swing, and up-close and personal views with the famed City Museum Schoolbus and Praying Mantis, among other things. Rogue roosters have been known to strut past surprised visitors.
