[TowerTalk] Guy anchors in rock

[Dino Darling]

Sure.  But there is always that level of UNKNOWN.  We have big 
boulders rolling down the hills here in Southern CA all the time.

At the very least, be willing to loose the tower system and if it 
falls, make sure it doesn't hit anything important.  My GUESS, is it 
would be good for the rest of your life, but that is only a guess.

There is a guy in Colorado (can't remember the website) who had his 
tower foundation mounted onto a big rock.  He had an engineer check 
it out, bored holes into the rock and used epoxy to secure the 
rebar.  As far as I know, its still vertical and working perfect.
