and if you are going overhead like I do just use a piece of guy wire as the
carrier and connect it to the ground system at both ends.

Agreed..
I think the other discussion is whether it is worth running another
parallel conductor from tower to shack (where tower and shack aren't
co-located) to bond the ground system of tower to ground system of shack.
I'm not sure that's worth it. OTOH, if you're already digging a trench,
laying conduits, buying multiple runs of hardline coax at a dollar a
foot, maybe adding a bonding conductor, and burying it separately, isn't
a big deal.
