[TowerTalk] Square Hole or Round Hole for Self Supporter?

[Richard Thorne]

Clay,

I emailed a fella by the name of Jeremy.  He quoted me $2800 for a 10' hole.

 From the other post's on the subject probably a reasonable number. I'll 
still research the back hoe method.  I'll bet will be less expensive to 
use a back hoe and have the dirt hauled off (if needed).
