That really is the point. Yes guests can be animals, but that is no excuse for leaving the monorails to rot. If things are maintained properly guest behavior can be controlled and their impact negated.Dave, you're right that a lot of things are on the guests, but what isn't are the things like the rust and chipped paint from wear that is on the interiors that I've seen in person. There is no doubt that people are rather disgusting compared to the past with a lack of decorum, but it's hard to honestly tell how much worse than in the past because Disney did such a outstanding job of cleaning and maintaining everything on a daily basis.
