I was there last weekend, and they have all the footers in, most of the track on the ground, and one piece up already.
It's not as close to IJ as it looks in the photos.. I think the main issue will be draining out the pond there to do the work they need to do in there.. (though it looks like the footers are already in the pond, as well).
However, my concern is what they will have to do to a normally smooth and sub-forcey B&M to turn it into a painful, kidney punching, shoulder dislocating, chin smashing ride like the rest of their stable!
(Seriously.. it was my first trip to CW.. and although I'm happy for the credits.. most of those rides are _painful_. Vekoma certainly has the knack for ride design.. but good LORD the restraints on Top Gun are ridiculous! And don't _even_ get me started on Dragon Fire or the two woodies!)
To be fair.. Italian Job, Vortex, Thunder Run.. those are pretty good, fun rides. But Sky Rider took a large chunk out of my left thigh.. have those designers at ToGo ever heard of a transition that isn't a 90 degree jerk?
