We do a lot of ground rod driving around here with air compressors, that does lead to some major mess ups.

A friend of mine was driving the 10' rod, it was going in pretty tough, just as he got to where he could stand on the ground, he thought he felt something..... he did, the rod made a u turn underground and came right up his pants leg.

It's a fairly common thing for them to turn around and come back out..... ya only need one rod, tell the inspector ya drove 2. [Linked Image]
