I'll see if I can get some.

I ran into another real problem today. Well, TWO problems, actually.

1) I have **extremely** rocky soil. For most of where my ground wires 
run I can't get an edger blade in more than 1/2 an inch to an inch!! 
How can I even hope to accomplish a ground with this kind of soil? 
What if I just dump 2" of earth on top of the wire and put down grass seed?


2) After trying for 3+ hours, one strategically-placed ground rod 
would only go in on a 45 degree angle. I tried a cadweld shot on 
there and it just ran out the side hole in the mould, melted RIGHT 
THROUGH the wire and, when it all cooled down, I had two wire ends 
and a heap of slag in the hole, and the thin wire from the mold 
welded to the top of the rod. It was NOT possible to drive that rod 
in anywhere within 5' vertically.



Cheers,
