In fairness to RCDB, they have been much more on the ball with regards to listing SW8. Also, they are probably the best we’ve got in terms of logging coasters worldwide.The irony of this being on RCDB three years before it will be built, when The Smiler wasn't listed even 3 months before it opened!
Does RCDB not only listed near enough confirmed coasters and don't remember anything from EP to suggest a new coaster?
I believe that is Roland's garden.That's interesting although again not much space to work with in those areas. Behind Crazy Taxi in England is however a fair bit of land but again not sure if EP own that as it looks like a garden with a swimming pool!
