[TowerTalk] AB-577 Surface Guy Anchors?

[Robert West]

I like the hitch idea.  As long as no one "forgets" and drives off with the
tower!  This would be a 4 or 5 day setup but I guess if we found folks who
aren't planning on going anywhere that would be ideal  But would have to
have them on-board for that at least a week prior.

It would have a lot of bearing on the guy points.

Actually the tires of a car/truck/SUV would give much more gripping 
power than the metal "boats" mentioned.
In Robert's group there must be several who own pickup trucks and/or 
SUVs. Most, or many have a 3 point hitch on the back. Any of them 
configured for towing would have a hitch that could be used, rather than 
looking for a winch.  However they would need to tie around the mount 
and not the ball as a rope or cable can easily slip off the ball.
