Very interesting. Where is the lift and to what direction is it oriented? Does it look like it will dive into that valley behind hobo junction like I thought earlier? A 70ft lift + another 50ft or so change in elevation could make for a nice drop, and further elevation drops down the valley could make an interesting layout that gets faster as you go along. The first drop might not even be the largest.
As for the leanness of the frame, the probably have just set up the bents and haven't added all the cross ties yet.
Is the track on site visible from the usual vantage points? I didn't know they were keeping that a secret, but if so I hope we can all agree to follow the park's wishes as best we can. Someone is going to spill the beans pretty quick if it's out there though.
