There is some space to put some rides and a good sized coaster behind Son of Beast, you probably already know this but when i was reading my coaster book(which could be old and something could have been built there since and i dont know because i havent been to PKI) and a picture of Son of Beast came up and they showed the space behind the coaster and there is quite a bit.What do you think will go there and if you wanna see the picture, i think i can scan alittle bit of it, it is a big picture, just PM me.
