I laugh at how cleverly the CGI designers hid the poles. You can see the shadows of them in that video very well, but have to look hard to see the poles themselves. From what I've seen in pictures those poles are pretty nasty.
I asked my dad once why there were no electric poles and lines in Disney. His response was because they got so many storms in Florida it made more sense to keep it all underground. I was so impressed, it was magic to me that they could hide the stuff like that. Apparently somewhere along the lines with the newer imagineers coming along and trying to put on bigger, more impressive shows, they forgot that giant telephone poles and theme parks don't mix, unless it's in an area intended to have that visual clutter. They could at least add a themed tarp to them
I am not looking forward to seeing them this summer: Tink's zipline irks the h3ll out of me. [overreact] I fear these poles will cause me to rage to the point of bringing in the lumberjacks to saw them down. [/overreact]
