Oh, why didn't you guys tell me you wanted to know what it was like to climb a tower...thanks to YouTube we can do that as well. Thankfully however, it is a virtual thing.
Here is a very cool video. It is a bit long, but it shows what it is like to climb to the top of a 1700 foot radio tower to change a light bulb. Up until I saw this video, I thought changing the recessed ceiling bulb above my parents stairway was a challenge. In parallel with this climb however, that really is not so bad!
For those that have no time to view the entirety...1:35 seconds in is a great place to see the climber transition into free climb mode, and surprisingly it is allowed by OSHA...that is, no safety harness required. Other quick areas to see are 3:30 to 4:00 minutes in, and around the 7:00 mark.
