[TowerTalk] misaligned vertical towers

[David Gilbert]

I truly do not see the quandary here.   You don't need a plumb bob 
hanging off the tower ... just hold a plumb bob out in front of you as 
high as you can hold it and line the string up with the towers one at a 
time from various vantage points.
