SFGAm's 40th Anniversary Season will be in 2016, so I'll save the generic revitalization efforts until then. (I want them to follow a KD type route for that year, repainting rides, refurbishing, landscaping, and possibly brick paving.)
For 2015, I'd like to see either a SkyScreamer or a Screamin' Swing in the spot vacated by Ragin' Cajun. Giant Barn Swing was fantastic and I'd love to see one of them at my home park. I also love swing rides and heights, so I think a StarFlyer would be a perfect ride type for somebody like myself.
