I thought I had mentioned this up thread but maybe I only thunk it.it is a common practice here Coobie. Every pole, before it is set has a spiral wrap on the bottom of the pole with the #6 wire. Of course it is stapled all the way down the pole and then the spiral wrap on the bottom of the pole.
Me, either, but I wonder if it has a lot to do with the soil depth that you can expect a reasonable ground at. Soil that is too dry / too sandy / too rocky isn't going to function well.Never seen that before here in the north country ..
