On trip through Minnesota, I watched a helicopter ferry guys up onto the towers to work (they dangled from the helicopter and then transferred over to the tower: http://www.capx2020.com/ ). They were building the type of infrastructure the news says America doesn't know how to build anymore.

I wonder if energized lines are the big problem.

Workers can safely work on live high voltage lines, if they're wearing a Faraday cage "hot suit" and not grounded: http://youtu.be/LIjC7DjoVe8

That video is awesome. I've seen a version with much better quality that really gets my acrophobia going... ;-)
