[PVRCNC] Guys in rock

[mike at bentwire.net]

No, this isn't a hair metal band related question. 

Does anyone have any knowledge/experience with installing a guy anchor 
in solid rock? I'm contemplating a tower project and the location for 
one of the guy anchors is in an area of large granite slabs. Seriously, 
the creek that runs along my back property line is cut entirely into 
granite. At first I despaired the thought of jack hammering out rock to 
place an anchor post, but then I realized that they do install anchors 
in solid rock by drilling and epoxying the anchor or use some sort of 
expandable bolt thingie. Anyone have any experience with that sort of 
thing? I'm looking for knowledge right now, wisdom will hopefully come 
later.
