[TowerTalk] Guy anchors in shallow soil

[Linux Mercedes]

The tower base is a self-designed dirt base; I dug the hole with a 12" 
auger. It's buried about 36" deep.

I was hoping to end up with an easily-removable tower, but I think 
concrete anchors are going to be the way I go with this.

Somewhat relatedly, there is one tree maybe 2' in diameter near one of 
the guy points; do you think I could drill a hole through that and use 
it as a guy anchor point?
