I'm going tomorrow, so I'll keep my eyes open for that!
Edit: Went today, did have a look around, couldn't see any track anywhere, I think they've hidden it now. The construction on site, however, seems to be at a fairly advanced stage in terms of the ground work. I didn't go on Rita today and the sky ride is closed this season for obvious reasons, so I didn't get a decent view of the site, but I could make out footers in the trees and leading up to them and there was a fair bit going on with 4 cherry-picker, crane style vehicles moving around the site all day.
Edit 2: saw this on RCDB and it made me chuckle
Call me sad, but it made me chuckle to think that the name might not have to be changed ever, haha.
ALSO, does anyone know of anywhere that is actually following the construction, because all the towers enthusiast websites don't seem to have particularly regular uodates, and the construction is now about to get interesting!
