A fun thing to do is measure the resistance between individual ground rods in a
group, and between any rod and the tower, *before* connecting the ground rods
together and/or to the tower base. In our case, 4 rods in clay soil, damp year
around below a foot or two, and having only a good digital ohmeter (but no
megohm meter), the indicated "readings" drifted continually from a minimum of
like 1K ohms up to over 10K ohms, never did stabilize between any pair, must
breakdown/change dramatically during a strike? Not exactly inspiring of
confidence however...have heard mention of periodically salting the area around
a tower to make the ground really "play."
Would sure be interesting to know how all the resistance/impedance is actually
distributed (and changing) among the rods and tower base during a solid
strike...??

Yeah, and that's a problem, because the code requires 8 feet to be in
contact with the soil. [-SNIP-]
