SFOG 5-year plan:
2015: General ride improvements and staff training, including shock collars that zap them if they take too long to dispatch a train, deny a ride to a child who is tall enough, etc.
2016: People are just gonna get tired of Mindbender, because it's old and stuff, so why not get rid of it and build a custom terrain Volare? It can be Nightwing themed. Talk about new and fresh!
2017: Take the floors off of the trains on Scorcher, but leave the standing restraints and bicycle seats. Also make a soundtrack similar to It's a Small World for Monster Mansion. While I'm at it, I think a facelift of Monster Mansion would be nice. And make the ride last for two hours.
2018: Take out Batman and Superman. Replace Batman with two Boomerang coasters facing opposite directions, call them Batman and Robin (yes, I know Nightwing and Robin are the same hero, but the GP won't know). Replace Superman with a dueling AquaTrax themed to AquaMan (since it's so close to the water park).
2019: Goliath is gonna be really old at this point (13 years!), so get rid of it and replace it with a S&S free fly. The GP will be astounded at the amazing capacity of this ride, and will also fall out of the ride because they're Americans, therefore they are above park rules.
2020: Take out GASM, replace with a 6000 foot long Roller Skater. Get rid of Dare Devil Dive, replace with an Intamin First Gen Drop Tower (like what was there originally). Add a 60 mph launch to Dahlonega Mine Train, but keep the original layout, because it's a classic Arrow.
I think that covers it. I think all of these will be major improvements to the park, and will boost attendance and profits by 500%.
