I couldn't figure out which pictures of the trestle to keep and which to pitch.  Ultimately, I couldn't bring myself to pitch any of them.  Each shows its share of new detail.  Take this picture, for instance.  You can clearly see the ladder extending form the base up to about the 3/4 height mark.  There is also the remnants of a catwalk still evident on the first level down from the track.  The aforementioned band of knuckleheads are still picking their way from left to right.   And they are still cursing whoever talked them into the 'experience'.
