Since spring crews have been working on burying a power/communications cable parallel to the Cog. (One of the more intriguing results of this is the creation of a service road.) There's a great article on the project in today's Concord Monitor (10/3/07).
Here's one of the images I got recently while documenting the project. There's are few more at http://www.lakesregionaerials.com/MtW_wired/list0.html.
