I had an idea for if PKI expands in Action Zone...remove Congo Falls and possibly Timberwolf (they could always build a new theatre), at this point they could put a ride in this old combined site, complete the path loop around Drop Zone, redo Top Gun's queue so that it is entered from the Timberwolf site, and then there could possibly be a space for new path under TG next to SOB.
This plan would be of use for later expansions since AZ is not really in need for expansion right now.
My idea for Ghoster Coaster: Since it seems that NC will take over HBL next year, I see three options for SGC
1. Remove it altogether since it has bad capacity and almost anything that took its place would have better capacity...even a SpongeBob coaster (which I think would be better anyway)
2. Retheme it to Fairly Odd Parents...after all it suits the suspended coaster type better and it is what Carowinds did to their Scooby coaster
I kinda hope its the first one but that's my opinion. I also hope that the Slime Zone isn't removed as it kinda is NC's central attraction (no pun intended) in terms of land. As to the Screamscape rumor, I think its probably false.
