I laid some wires (not enough) down before I laid the sod on the quasi
prepared dirt...

Hey, there's a new feature for new housing developers...  (you wouldn't want
them to think radio.. capitalize on some other perceived thing.. maybe
"currents of death"?)

Preinstalled ground mesh in the yard!

Shield yourself from EMI, etc. (after all, most utilities are underground

"This exquisite 4br,3ba home has granite counter tops, a built in spa in the
master retreat, and a complete shielding network to protect from radiation
fields from the underground power lines. Think of your children playing the
yard. They're much closer to the high power wiring buried by the utility
company in that 10 foot wide easement across your 5000 square foot lot."
