[TowerTalk] World's toughest fixes - 2000' tower

[Jim Miller KG0KP]

OK, I have to say it.  I was up 54 feet and to me that's a mile.  Working to 
take down a tribander and trees all around that had grown through the tower 
and up and into the antenna.  Calm day, mostly, a gust of wind moved all the 
tree tops in unison and I thought the tower was falling.  I grabbed the 
tower hard enough I thought I bent the top.  Not sure what that was supposed 
to do except keep from bouncing once I hit the ground.  Anyway, scared the 
cr-- out of me.

73, de Jim KG0KP
