I visited Alton Towers yesterday to ride Sub-Terra (BTW scared witless ahah). I checked out SW7's construction area, but my iPhone ran out so I have no pictures but good news there was a concrete truck there and the metal mesh that they use when laying concrete so I presume its either work on the station and buildings or the footers, but either way its still exciting. Sub-Terra surpassed my expectations but I feel there should be more signs warning about how overwhelming it is, I had to help a little boy out because he was crying, but nonetheless I thought it was brilliant, the drop should have been deeper though, would had made it amazing, either way it certainly is unique ;D
