I never had a reason to check voltage to earth,but i was checking the voltages at a site light and my one lead was stabbed into the ground when i noticed i was getting a reading.The earth was very moist from all the rain we've been having.So i guess that there must be some good grounding going on.The utility service riser pole was close by, but the indoor equipment was a 100' away.Have you guy's found the same other places.
