They did that a week before opening, right now they are in the process of painting the supports green/blue. Also, High roller got a new coat of paint, we got a new kiddie coaster (credit:D), a kiddie monorail, etc.
^ Yep, to tell you the truth though, it looks the same to me.... Corkscrew actually looks WAY better with green supports. With white supports it still reminds me of blue corkscrew.
