I think the initial plan was that those two were still in good enough shape that they could potentially be sold like the two that were sold to Las Vegas. The cars were full of all the remaining extra parts too. The warehouse was pretty amazing I could have spent a few days just taking everything in. There were ride vehicles, movie props, AA's including a whole row of Figments, Models of things that did and didn't get built and yes there were also plenty of napkins and various other ordinary supplies.
I can only imagine seeing Universal's equivalent of this. All those HHN props that must be there! One day maybe if I'm lucky...
