I just thought of this. There are coasters at some parks, very few, that have moving parts next to the tracks, to enhance the theme. I was thinking SDC could do something like add Wooden Boards that go up and down, controlled by one of those door closer things. For example, after Thunderation comes out of the tunnel, to add a more TNT effect, 2 boards that are next to the tracks can go down right after the train comes out of the tunnel. When the boards go across the tracks, it looks more like something has been blown up, then go back up to wait for the next train. They could also do this on another coaster, but I can see it happening on Thunderation more than any other ride, even though most people wont even notice it.
