[SBE] conversation topic: how often do you check tower ground wires?

[Bill Burckhard]

We don't have a lot of lightning here in Billings MT. We have been tying the
bottom of the tower into the ground system that is also used for the
transmitter. The transmitter building has ground strap that is tied to
ground rods and goes underground all the way around the building perimeter.

Those buried radials won't last forever. Copper, turning green, then dust.
So 
what is the thinking on how often to dig one up and check the condition, or 
measure the ground resistance?  How about those that are not AM towers
(ground 
effectiveness can be gauged by field strength on radials), but your typical 
1000', 2000' 
tower lightning protection ground system?  Didn't use copper because someone

steals it?  Ground rods vs radials?
