Not at all. 
 I spent some time comparing "artist's renderings" to the pictures we got yesterday.  Based on that, here's what I 
think we saw yesterday (actually some of this is pretty obvious):  
o  The supports for the turnaround at the bottom of the 2nd hill, and the 3rd hill, are going in.  
o  The footers for the final approach to the station are in.  
o  The footers for the final turnaround/helix before the approach to the station, are still under construction.   
Since we weren't in the park, can't say much for the trench/tunnel, or the section over by the Turtle.
