is better conductor than gravel when wet. Sand and gravel by itself
(dry, that is) are excellent insulators, not good for ground. If you go
to a major electrical substation you often see gravel all around,
especially around the fence lines. Its a good insulation and could
prevent you form electrocuted.

In most places gravel is placed instead of grass. There is very little
upkeep on it. Just squirt it with some roundup to keep the grass out.

It has nothing to do with insulation.



Sure it does, just look up substation grounding, step and touch potential,
IEEE and other articles on grounding and gravel.
