Some people are going to be physically unable to watch this video. Others will find it thrilling and might even want to try this themselves. Which category are you?

Cool vid.  Back in another life I worked for a cell company.  I *always* hired tower pros.  I never climbed even our shortest towers.  Not even once.
 
 

I didn't have trouble watching.
Years ago I had a job that required climbing 180' four times a day minimum -nothing compared to them but I know how tiring climbing can be.
Offered a seven digit amount of dollars a parachute and no time limit I'd attempt it.

I am not ashamed to place myself in the NFW category. I don't even like being on the roof of my house.

I watched that a while ago, amazing stuff. I'm fine up scaffolding, on the roof, cherry-picker, scissor lift etc, but on a ladder I get to the 'rung of doom', and can go no further.

Double bubble.

I probably would have less of an issue climbing the tower than some roofs.  The towers have a measure of security while, at 6' 4", 250 lbs., I always feel like I'm moments away from sliding off a roof.
 
One of our clients does the climbing for all things tall, radio towers, water towers, etc., and we're always having to set up new laptops for them because they'll take one up then accidentally drop it to its death...  LOL!

ummafeard of hites.
 
DW.

The most fun is getting all the way up there then imagining that you lose your grip. 
 
Remember that wonderful feeling you get that goes down your spine?  Ohhh yeahhh! 

Is there a bacon sammich at the top?  That might change things.
