Seen many pictures like that over the years.
They give me heebie jeebies. Literally make my feet tingle just looking at them....
I hate heights....
At 6-8, I was required to help hang blower pipe on silos.
Lacking silo unloaders, also required to climb the door ladders to throw silage down all winter. If you've never tried that, it's an experience going up 30 or 40 feet on wet slippery rungs with rubber barn boots...
Didn't like heights then, and as an older adult it's probably a phobia.
I still have the 32 foot ladder we used to clean the wood stove chimney on the farm. Had to stand on the second rung to clean it - hugged the chimney...
No reason I should have a 32 foot ladder anymore.
If I were a roofer, I'd starve.....
