[TowerTalk] Rohn Tower Damage Pictures

[Jim]

I must be looking at different pictures then.  I can see daylight quite a ways into some
of the 'weds'.  They certainly look insufficient to me.  I'd be leary climbing on those
braces.  Of course, I don't climb anyway but if I did, I'd be leary.  Maybe I
misunderstand the engineering requirements of the welds but I'd think they'd need a bit
of bead on both sides, not just the outside.  Just my opinion, right or wrong.
