[TowerTalk] Concrete anchors

[Patrick Greenlee]

I would go for the adapter plate as a simple straight forward solution 
with no esoteric chemistry involved.  Had I had years of successful 
experience with chemical anchors and super confidence in the strength 
and condition of the top layers of the concrete, I would probably go 
with the adapter plate.
