Also as far as land goes, they have several options open before they *need* to start removing rides for future rides. There is quite a bit of open land that can be freed up just by moving a ride, like Whirligig being moved for V2 and Ameri-go-round for a Frisbee-go-round. Also there are stretches of wide open land, like between Viper and the railroad track, while not much land in width there it is plenty long and any coaster designer worth their weight could design something nice for that area. Also back by the coca cola cool zone in SWT I have always felt (at least since 96) that that spot was prime for a relatively large flat ride of some type. PGA has nothing against building rides directly over thier Access road in the middle of the park, nice scenery from the Vortex loading station, a huge building with PARK OPERATIONS written in big bold letters across it and maintaince vehicles whizzing by underneath you. Yukon Territory right now is like a nearly clean slate, tear out that generally unused Wilderness Theatre and you got quite a chunk of space back there, not to mention a bunch of undeveloped smaller spaces or spaces with a shop taking up a bunch of room. While not alot of room there is space behind theatre Royal and Pizza orleans, though anything there over 125 feet and you may refer to the angry locals with torches and pitchforks again. Also coasters can be built out into the parking lot starting at the back of Pictorium around the shuttle to the front gate, if odne right you could probably use that space for 2 coasters. And all this is keeping the park generally within it's current boundries (i.e. not expanding the actual park with midways into the lot).
And if they take a visit down to IB like someone else mentioned, they could easily double and tripple the ride count and not remove a single ride and have plenty of room to spare. SFGAm is still on it's first level of rides, and if you look at all of Blackpool Pleasure Beach there are rides on 4 seperate levels in the park(I dare anyone to not get lost there on their first visit).
It will take a long time for SFGAm to completely run out of space, the only threat is them running out of ideas
