Oh my gosh. Here's an amazing helmet cam video showing an engineer climbing to the top of a 1768 ft transmission tower; part of the way without any sort of safety harness or anything. (There's a 17 second pre-roll opening credit first.)
The good news – on a clear day, you can see 55 miles in all directions. The bad news – well, guess!
Best viewed on up close to a big screen. Not!
