I was all excited about this myself, so I made it a point to be around CL during the entire time period that one could consider "dusk." Around 7:25 or so, standing next to Flo's, I turned around to take a few photos of the beautiful rock formations that are part of the RSR ride, and when I turned back around the lights were on. I guess it must not have been an exciting experience because I missed it entirely and I was standing right there.
