See How The Grand Canyon Skywalk Gets Clean

For those of you who've been to the Grand Canyon, you might recognize the Skywalk. For those of you who haven't seen it. They've built a glass path that goes out over a cliff for an even better view of the Canyon.  Well glass gets dirty, so someone has to clean it.

The company that gets to clean the more than 40 panes of glass is called Abseilon USA out of Phoenix.  Have a look at their cleaning setup.  My question is, can you have too many ropes?
