Amen to that. One of the local guys was seriously hurt when a tower he 
was taking down fell with him on it. One of the turnbuckles parted. 
The widow said the husband used only stainless steel hardware. This 
turned out to not be true.

And keep in mind that towers made with tubing rot from the inside out. 
You can't check the outside and know if the tower is in decent shape.

A local ham, as well as business-band tower owner, looked up at his 
tower one day and saw that one leg was bowing out. This was tubular 
tower as in the Rohn 45 or 55 stuff. He replaced it with a tower made 
from solid rod. There is no 'inside' to rot with solid rod.

Since one cannot see the inside of a tower leg, and since tubing rots 
from the inside out, it is good to be cautious.

If I were going to climb an old tower I would guy it securely every 
10' on the way up. I dunno that that would prevent it from collapsing, 
but it would go a long ways toward preventing that. Old tower is 
dangerous stuff.
