A note about the railings... I'm pretty sure the ride vehicles will pass through this area, on their way from the load rooms to the first scene. The railings aren't to keep us from touching the AAs, they're to keep us from getting run over. Notice how much space is between the railings and the AAs. That might be for the RVs to pass by. After all, there is no track, so it's hard to tell, but that's the first scene of the ride, technically. (Or, so I have heard.)
