That's cool to know it's either already been brought up here and/or at HFEC. Whether it meandered through the beautiful wooded Ozark terrain, whisked guests above the trees for a birds eye view between sections of the park, or offered a connection via some sort of themed tunnel, I think a well done people moving system could be a very cool addition in its own right. But I'm getting way ahead of myself.
It's probably safe to say an entire new section of the park won't become a reality at once. If it happens at all, I envision a new area evolving around a new major ride/attraction.
In true SDC fashion, I think the major additions to the park this decade (WF, PK, TGS, GE & RB) have all been done with impeccable attention to detail so I too am confident that whatever major addition comes next will not disappoint.
Just wish we had an inkling what the heck it's going to be, where it's going and when we can expect to start enjoying it.
