They wanted slides to be exploding out the back side seeing as how the front side is just mountain....Essentially, the colorful slides coming out of the back is a visual difference between the front...Seeing as how you don't see any slides when you first walk in (besides the giant drop one and a little bit of some), it is an intentional design change when you circle around back to where you get on the slides. Maybe they felt the park would have felt more empty with everything being enclosedI don't get the logic behind that decision. Make it look worse and cost more?
TBH my biggest issue is with the garrish metal work that you see...Was it too much to spray some concrete at it?
