I guess that answers my question.

But speaking of catenaries, I remember the first time I ever heard that word. My dad went to a trade school type thing for land surveying around the time the Batman series (with West) came out on TV. The whole class begged the prof to be let out so they could all go watch the premiere. The prof let them go, since I think he wanted to see it, too. That episode showed Batman and Robin climbing up the side of the building, and there was a catenary in the rope that was supposed to be dangling straight down. Apparantly no-one ever asked the prof to get out of class to watch it after that.
