I've never paid attention to the tool they use
when they put up the tent at the Charlotte show,
but it'll drive a 1 inch solid tent stake through
the asphalt parking lot like it's butter.

I've never been there to see what they have to do to pull
them out when the tent comes down.
The stakes sure hold the tent fine.

I'd like to drive a ground rod near the point where
the coax hooks to the ladder line from my G5RV,
but it's next to a large oak tree.
I can just imagine what getting through all those
roots would be like.
==============================
Having followed this thread for some time , my simple question is :

Are ground rods really necessary for a good " RF Earth " ?

Are buried or elevated radials or an area covered with '(galvanised)
wire mesh' not equally effective or even superior ?

For RF purposes, radials or mesh are more effective than ground rods.
Radials and mesh form a 'mirror' surface at RF effectively reflecting an
image of the elevated antenna radiating element. It is not necessary to
actually have a 'good' connection to real earth, just the antenna system.
This is why elevated radials can work.

The radiating portion of the antenna needs something to 'work' against. So
you have two choices, a monopole antenna which can be thought of as working
against it's reflection in the earth, or a dipole antenna where each antenna
element works against the other. Just about all antennas are variants of
these two methods.
